This episode features The Devotion of Suspect X by Keigo Higashino. Spoilers are between the 40 – 1:33 minute marks. We discuss the different layout of this book compared to other mysteries and thrillers and how a lot of our characters aren't as important as they usually are in books. In spoilers we talk about the genius of Ishigami and Yukawa and how both kept us guessing throughout. We end with our usual segments and another surprise book for the next show. Enjoy!

Constraints on Yukawa gravity parameters from observations of bright stars by P. Jovanović et al. on Thursday 24 November In this paper we investigate a Yukawa gravity modification of the Newtonian gravitational potential in a weak field approximation. For that purpose we derived the corresponding equations of motion and used them to perform two-body simulations of the stellar orbits. In 2020 the GRAVITY Collaboration detected the orbital precession of the S2 star around the supermassive black hole (SMBH) at the Galactic Center (GC) and showed that it is close to the general relativity (GR) prediction. Using this observational fact, we evaluated parameters of the Yukawa gravity (the range of Yukawa interaction $Lambda$ and universal constant $delta$) with the Schwarzschild precession of the S-stars assuming that the observed Schwarzschild precession will be equal to their GR estimates. GR provides the most natural way to fit observational data for S-star orbits, however, their precessions can be fitted by Yukawa gravity. Our main goal was to study the possible influence of the strength of Yukawa interaction, i.e. the universal constant $delta$, on the precessions of S-star orbits. We analyze S-star orbits assuming different strength of Yukawa interaction $delta$ and find that this parameter has strong influence on range of Yukawa interaction $Lambda$. Using MCMC simulations we obtain the best-fit values and uncertanties of Yukawa gravity parameters for S-stars. Also, we introduce a new criterion which can be used for classification of gravitational systems in this type of gravity, according to their scales. We demonstrated that performed analysis of the observed S-stars orbits around the GC in the frame of the Yukawa gravity represent a tool for constraining the Yukawa gravity parameters and probing the predictions of gravity theories. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.12951v1

Astrophysical Observations of a Dark Matter-Baryon Fifth Force by Moira I. Gresham et al. on Sunday 11 September We consider the effects of an attractive, long-range Yukawa interaction between baryons and dark matter (DM), focusing in particular on temperature and pulsar timing observations of neutron stars (NSs). We show that such a fifth force, with strength modestly stronger than gravity at ranges greater than tens of kilometers (corresponding to mediator masses less than $10^{-11} text{eV}$), can dramatically enhance dark matter kinetic heating, capture, and pulsar timing Doppler shifts relative to gravity plus short range interactions alone. Using the coldest observed NS and pulsar timing array (PTA) data, we derive limits on fifth force strength over a DM mass range spanning light dark matter up to order solar mass composite DM objects. We also consider an indirect limit by combining bullet cluster limits on the DM self-interaction with weak equivalence principle test limits on baryonic self-interactions. We find the combined indirect limits are moderately stronger than kinetic heating and PTA limits, except when considering a DM subcomponent. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.03963v1

The hard-disk model has exerted outstanding influence on computational physics and statistical mechanics. Decades ago, hard disks were the first system to be studied by Markov-chain Monte Carlo methods and by molecular dynamics. It was in hard disks, through numerical simulations, that a two-dimensional melting transition was first seen to occur even though such systems cannot develop long-range crystalline order. Analysis of the system was made difficult by the absence of powerful simulation methods. In recent years, we have developed powerful Monte Carlo algorithms for hard disks and related systems. I will in particular show how the event-chain Monte Carlo algorithm has allowed us to prove that hard disks melt with a first-order transition from the liquid to the hexatic and a continuous transition from the hexatic to the solid. I will finally describe how a new factorized Metropolis filter transforms the event-chain algorithm into a paradigm for general Monte Carlo calculations. First results with the generalized algorithm have allowed us to establish the phase diagram for two-dimensional soft disks and Yukawa particles.

Purpose of this series: “To facilitate a discussion of the multi-cultural/ ethnic identities of Japanese-Americans living in Japan. The aim of this podcast mini-series is to center a conversation around how our guests` Japanese-American experience in the West has transformed and re-translated into their current experience living in Japan. Documenting these person-specific stories creates a safe space to foster community in similar experiences, while celebrating the diversity within the Japanese American identity sphere. Each story is accompanied by their own experience of identity crisis and the resilience born in the struggle. Let us deconstruct the narrative around Japan`s racial homogeneity and encourage a healthy perception of one`s Japanese-American self-image by rooting in first-hand accounts of millennials via the Japanese diaspora.”

Over the past two years, CERN's Large Hadron Collider (LHC) has started to directly probe a qualitatively new class of interactions, associated with the Higgs boson. These interactions, called Yukawa interactions, are unlike any other interaction that we have probed at the quantum level before. In particular, unlike the electromagnetic, weak and strong forces, they have an interaction strength that does not come in multiples of some underlying unit charge. Yukawa interactions are believed to be of fundamental importance to the world as we know it, hypothesised, for example, to be responsible for the stability of the proton, and so the universe and life as we know it.

In this episode, we follow the development of the strong force from Yukawa through to the work of Murray Gell-Mann and Georg Zweig and the first quark-gluon model of matter.

In this thesis we study the geometry and the low-energy effective physics associated with Abelian gauge groups in F-theory compactifications. To construct suitable torus-fibered Calabi-Yau manifolds, we employ the framework of toric geometry. By identifying appropriate building blocks of Calabi-Yau manifolds that can be studied independently, we devise a method to engineer large numbers of manifolds that give rise to a specified gauge group and achieve a partial classification of toric gauge groups. Extending our analysis from gauge groups to matter spectra, we prove that the matter content of the most commonly studied F-theory set-ups is rather constrained. To circumvent such limitations, we introduce an algorithm to analyze torus-fibrations defined as complete intersections and present several novel kinds of F-theory compactifications. Finally, we show how torus-fibrations without section are linked to fibrations with multiple sections through a network of successive geometric transitions. In order to investigate the low-energy effective physics resulting from our compactifications, we apply M- to F-theory duality. After determining the effective action of F-theory with Abelian gauge groups in six dimensions, we compare the loop-corrected Chern-Simons terms to topological quantities of the compactification manifold to read off the massless matter content. Under certain assumptions, we show that all gravitational and mixed anomalies are automatically canceled in F-theory. Furthermore, we compute the low-energy effective action of F-theory compactifications without section and suggest that the absence of a section signals the presence of an additional massive Abelian gauge field. Adjusting our analysis to four dimensions, we show that remnants of this massive gauge field survive as discrete symmetries that impose selection rules on the Yukawa couplings of the effective theory.

In this episode we discuss the development of the first quantum field theories including quantum electrodynamics for the electromagnetic interaction, quantum flavordynamics for the weak interaction and quantum chromodynamics for the strong interaction.  We also touch on the work of Enrico Fermi and Hideki Yukawa.

In this Letter, we first demonstrate the existence of renormalization group invariant relations among the top, bottom Yukawa and the gauge colour couplings in the minimal supersymmetric SM. Based on this observation and assuming furthermore the existence of a renormalization group invariant relation among the trilinear couplings in the superpotential and the soft supersymmetry breaking sector, we obtain predictions for the Higgs masses and the supersymmetric spectrum.

The bulk matter Randall-Sundrum (RS) model is a setup where Standard Model (SM) matter and gauge fields reside in the bulk of 5D warped spacetime while the Higgs field is confined on the IR brane. The wavefunctions of the 1st and 2nd generation matter particles are localized towards the UV brane and those of the 3rd generation towards the IR brane, so that the hierarchical structure of the Yukawa couplings arises geometrically without hierarchy in fundamental parameters. This paper discusses an experimental test of this model in the case where the Kaluza-Klein scale is far above the collider scale, but the model is combined with 5D Minimal SUSY Standard Model (MSSM) and SUSY particles are in the reach of collider experiments. A general SUSY breaking mass spectrum consistent with the bulk matter RS model is considered: SUSY breaking sector locates on the IR brane and its effects are mediated to 5D MSSM through a hybrid of gravity mediation, gaugino mediation and gauge mediation.

A complex plasma is a suspension of nano- to micron-sized dust particles immersed in a plasma with ions, electrons and neutral gas molecules. Dust particles acquire a few thousands of electron charges by absorbing the surrounding electrons and ions, and consequently interact with each other via a dynamically-screened Coulomb potential. Dust particles in a complex plasma can be controlled through a low frequency electrostatic distortion. We studied the transport velocity of the particles as we modulate the frequency and phase of the applied voltage by a segmented electrode. We used molecular dynamics to simulate our experimental observations, using plasma conditions from independent particle-in-cell simulations. We found that the transport of dust particles controlled by low-frequency modulation in our simulations are in good agreement with our experimental findings. This work is in the aim of, on one hand, providing a potential technique for addressing the dust contamination issues in plasma processing reactors and on the other hand, providing a setup for investigating large two-dimensional complex plasma systems where boundary effects can be avoided. We then proceeded to study the non-additivity effect in a complex plasma containing two different sizes of dust particles (binary complex plasma). For dust particles of type 1 and 2, the 1-2 (inter-species) interaction is always more repulsive than the geometric mean of 1-1 and 2-2 interactions. This asymmetry in the mutual interaction is called positive non-additivity. We used Langevin dynamics simulations for the Yukawa interacting particles characterized by positive non-additivity. We found that the two types of particles can separate into fluid-fluid phases and the growth of characteristic domain length follows a simple power law with an exponent of about 1/3 until the coupling strength is small enough, which is in a good agreement with the Lifshitz-Slyozov growth law for the initial diffusive regime of phase separation. We then used Langevin dynamics simulations to probe the influence of non-additive interactions on lane formation. We revealed a crossover from normal laning mode to a demixing dominated laning mode. In addition, we found that the lane formation is strongly influenced by the exact spatial configurations at the very moment of contact between two different complex plasmas. We also used hydrodynamics to model the evolution of Mach cones in complex plasmas. The hydrodynamic model was able to reproduce a compressional-wave Mach cone observed onboard the International Space Station.

We derive predictions for Yukawa coupling ratios within Grand Unified Theories generated from operators with mass dimension four and five. These relations are a characteristic property of unified flavour models and can reduce the large number of free parameters related to the flavour sector of the Standard Model. The Yukawa couplings of the down-type quarks and charged leptons are affected within supersymmetric models by tan beta-enhanced threshold corrections which can be sizeable if tan beta is large. In this case their careful inclusion in the renormalisation group evolution is mandatory. We analyse these corrections and give simple analytic expressions and numerical estimates for them. The threshold corrections sensitively depend on the soft supersymmetry breaking parameters. Especially, they determine the overall sign of the corrections and therefore if the affected Yukawa couplings are enhanced or suppressed. In the minimal supersymmetric extension of the Standard Model many free parameters are introduced by supersymmetry breaking about which we make some plausible assumptions in our first simplified approach. In a second, more sophisticated approach we use three common breaking schemes in which all the soft breaking parameters at the electroweak scale can be calculated from only a handful of parameters. Within the second approach, we apply various phenomenological constraints on the supersymmetric parameters and find in this way new viable Yukawa coupling relations, for example y_mu/y_s = 9/2 or 6 or y_tau/y_b = 3/2 in SU(5). Furthermore, we study a special class of quark mass matrix textures for small tan beta where theta_{13}^u = theta_{13}^d = 0. We derive sum rules for the quark mixing parameters and find a simple relation between the two phases delta_{12}^u and delta_{12}^d and the right unitarity triangle angle alpha which suggests a simple phase structure for the quark mass matrices where one matrix element is purely imaginary and the remaining ones are purely real. To complement the aforementioned considerations, we give two explicit flavour models in a SU(5) context, one for large and one for small tan beta which implement the Yukawa coupling relations mentioned before. The models have interesting phenomenological consequences like, for example, quasi-degenerate neutrino masses in the case of small tan beta.

This PhD thesis is a cumulative dissertation that consists of three papers. The first paper describes the qualitative as well as quantitative nature of the electrostatic potential behind a macroparticle in a drifting collisional plasma and also the ion drag force taking into account plasma absorption on the grain surface. Plasma absorption on the grain surface is one of the fundamental properties of complex (dusty) plasmas which results in the "openness" of these systems. It is shown that in the considered regime plasma absorption determines completely the long-range potential. Physically, absorption of the drifting ions on the grain surface generates ion rarefaction behind the grain which opposes the ion focussing effect. In certain parameter regime ion rarefaction effect dominates over focussing effect which makes ion drag force to act in the opposite direction of ion flow i.e we obtain negative ion drag force. In the second paper both the ion drag and electron drag forces acting on an absorbing grain have been calculated in the limit of highly collisional weakly ionized plasmas. The plasma is exposed to an external weak electric field so that both ions and electrons drift with subthermal velocities. The effect of plasma absorption reduces the absolute magnitude of the ion drag force and even can change its sign in certain parameter regimes whereas this effect increases the magnitude of the electron drag force. The total force which is the sum of electric, ion drag and electron drag forces is proportional to the electric field. The proportionality constant represents the effective charge. The calculated value of the effective charge turns out to be of the order of the actual charge. This fact implies that in this parameter regime the drag forces are of minor importance compared to the electric force. The third paper deals with the isotropic potential distribution and the ion drag force acting on an isolated dust particle in highly collisional weakly anisotropic plasma. But unlike the previous two cases where plasma absorption and loss processes were neglected in the vicinity of the grain, in this work we consider these processes. The plasma production is assumed to be due to electron impact ionization whereas for the loss processes two different mechanisms are considered: in high pressure plasmas the loss is mainly due to electron-ion volume recombination and in low/moderate pressure gas discharges the plasma loss is due to ambipolar diffusion towards the chamber walls or electrodes. In the first case the potential consists of two exponential terms and the long range potential is of Yukawa type. In the second case the long range potential is Coulomb-like. It is found that the purely Debye-Hückel potential is obtained only in absence of ionization-recombination processes. The ion drag force is negative when the ionization rate is low, but becomes positive for sufficiently high ionization rate in both cases. The parameter regimes for the positive and negative ion drag forces have been identified.
