We are used to think about the universe as a structure which started with a Big Bang and then expanded. Sir Roger Penrose, who received the 2020 Nobel Prize in Physics, has developed an alternative theory of the universe based on Einstein's Theory of General Relativity which is called "Conformal Cyclic Cosmology". In this new model we don't have one single Big Bang, but an iteration of infinite cycles (or aeons) of expansion and cooling, each beginning with a “big bang” and ending in a “big crunch”. Science Journalist Jens Degett interviews Professor Niels Obers, Director of the Nordic Institute for Theoretical Physics (NORDITA) and professor at the Niels Bohr Institute in Copenhagen, on Roger Penrose's theory and how much evidence is needed in order to change the general view of a central paradigm which is written in our school textbooks. What if Penrose is right? What consequences or perspectives will it have for us?

Throughout the century that has passed since Ernst Ising submitted his PhD thesis in 1924, the Ising (-Lenz) model has provided an incredibly fruitful challenge that gave rise to entirely new branches of physics and mathematics. In this colloquium I will focus on the conformal bootstrap program which was designed by Polyakov in 1974 as a mathematical method to access non-perturbative aspects of critical systems/fixed points of the renormalization groups. In the light of holography, such systems are also relevant for the study of quantum gravity. In my presentation I will review some of the milestone achievements of the modern conformal bootstrap and outline current frontiers. The advances will be benchmarked mostly within the context of the 3D Ising model.

Causal invariance is one of the most important concepts in the Wolfram model... and one of the most difficult to capture.So I really wanted to hear Jonathan Gorard's take on it.In this excerpt from our conversation, Jonathan addresses the differences between causal invariance and confluence.Causal invariance means that regardless of the order in which a rule is applied to the hypergraph, the same events occur, with the same causal relationships between them.Confluence, on the other hand, is the coming-together of different branches of the multiway graph.Jonathan explores different ways we might determine whether two nodes, two edges or two hypergraphs are the same, and explains that if we identify nodes and edges according to their causal histories, then causal invariance and confluence become the same idea.I've found myself listening to Jonathan's explanation of causal invariance over and over to make sense of it, but it's one of the areas where I'm convinced Jonathan has a unique contribution to make.—Jonathan Gorard  • Jonathan Gorard at The Wolfram Physics Project  • Jonathan Gorard at Cardiff University  • Jonathan Gorard on Twitter  • The Centre for Applied Compositionality  • The Wolfram Physics ProjectConcepts mentioned by Jonathan  • Causal invariance  • Multiway system  • Causal structure  • Causal Set Theory  • Directed acyclic graph  • Isomorphic  • Space-like separation  • Simultaneity and simultaneity surfaces in relativity  • Lorentz invariance  • Poincaré invariance  • Conformal invariance  • Diffeomorphism invariance  • General covariance  • Confluence  • Church-Rosser Property—I release The Last Theory as a video too!

Today we're diving into conformal coating best practices. With the explosion of IoT, the electrification of vehicles, and the miniaturization of circuit assemblies and associated components, many of which are operating in harsh environments, the need for conformal coating has never been greater. Coating your assemblies? Where does one start? What material should one choose? Should it be applied in-house or through a contract-coating house? What are the best practices in materials selection, application, inspection, and thickness? So many questions! To answer these and other questions, Mike Konrad invited a conformal coating expert to shed light on this subject. David Greenman began his career in the conformal coating business at Concoat distributing Humiseal products and eventually manufacturing them under license for Europe, the Middle East, India and Africa. After 25 years of distributing and manufacturing Humiseal products, Chase Corp, which owns Humiseal purchased Concoat. David now serves as director of Humiseal UK, Europe and India, responsible for corporate responsibility as well as supporting HumiSeal sales and technical teams. He is qualified as a radio, TV/electronics engineer and a member of The Society of Radio and Electronics Technicians, now the Institution of Engineering and Technology.  

Conformal model for gravitational waves and dark matter: A status update by Maciej Kierkla et al. on Sunday 16 October We present an updated analysis of the first-order phase transition associated with symmetry breaking in the early Universe in a classically scale-invariant model extended with a new SU(2) gauge group. Including recent developments in understanding supercooled phase transitions, we compute all of its characteristics and significantly constrain the parameter space. We then predict gravitational wave spectra generated during this phase transition and by computing the signal-to-noise ratio we conclude that this model is well testable (and falsifiable) with LISA. We also provide predictions for the relic dark matter abundance. It is consistent with observations in a rather narrow part of the parameter space, since we exclude the so-called supercool dark matter scenario based on an improved description of percolation and reheating after the phase transition as well as inclusion of the running of couplings. Finally, we devote attention to renormalisation-scale dependence of the results. Even though our main results are obtained with the use of renormalisation-group improved effective potential, we also perform a fixed-scale analysis which proves that the dependence on the scale is not only qualitative but also quantitative. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2210.07075v1

Gauge/Gravity Duality 2013

Gauge/Gravity Duality 2013

We are used to think about the universe as a structure which started with a Big Bang and then expanded. Sir Roger Penrose, who received the 2020 Nobel Prize in Physics, has developed an alternative theory of the universe based on Einstein’s Theory of General Relativity which is called "Conformal Cyclic Cosmology". In this new model we don’t have one single Big Bang, but an iteration of infinite cycles (or aeons) of expansion and cooling, each beginning with a “big bang” and ending in a “big crunch”. Science Journalist Jens Degett interviews Professor Niels Obers from the Niels Bohr Institute on Roger Penrose’s theory and how much evidence is needed in order to change the general view of a central paradigm which is written in our school textbooks. What if Penrose is right? What consequences or perspectives will it have for us?

Join me for a very special discussion with Sir Roger Penrose, co-winner of the 2020 Nobel Prize in physics. We will discuss Conformal Cyclic Cosmology, Black Holes, and of course, Nobel Prizes! GET OUR SLIDES: https://kingsumo.com/g/vn03wc/sir-roger-penrose-on-the-into-the-impossible-podcast-slides Sir Roger Penrose is co-winner of the 2020 Nobel Prize in physics. We discuss Conformal Cyclic Cosmology, Black Holes, and of course, Nobel Prizes! Roger is a mensch. He always makes time for me and provided one of the first and most enthusiastic “blurbs” for my book, Losing the Nobel Prize.

Is the Universe destined to collapse, ending in a big crunch or to expand indefinitely until it homogenizes in a heat death? Roger will explain a third alternative, the cosmological conformal cyclic cosmology (CCC) scheme—where the Universe evolves through eons, each ending in the decay of mass and beginning again with new Big Bang.

M. Abstract: Soft, stretchable materials hold great promise for the fabrication of biomedical devices due to their capacity to integrate gracefully with and conform to biological tissues. Conformal devices are of particular interest in the development of brain interfaces where rigid structures can lead to tissue damage and loss of signal quality over the lifetime of the implant. Interfaces to study brain function and dysfunction increasingly require multimodal access in order to facilitate measurement of diverse physiological signals that span the disparate temporal and spatial scales of brain dynamics. Here we present the Opto-e-Dura, a soft, stretchable, 16-channel electrocorticography array that is optically transparent. We demonstrate its compatibility with diverse optical and electrical readouts enabling multimodal studies that bridge spatial and temporal scales. The device is chronically stable for weeks, compatible with wide-field and 2-photon calcium imaging and permits the repeated insertion of penetrating multi-electrode arrays. As the variety of sensors and effectors realizable on soft, stretchable substrates expands, similar devices that provide large-scale, multimodal access to the brain will continue to improve fundamental understanding of brain function.

Conformal interfaces are the long-distance limits of domain walls. They play a role in condensed-matter physics, and could be also rel- evant for theories of gravity. I will review some recently-developed techniques for analyzing their properties, and will discuss their pos- sible applications.

Teorías sobre el Origen del Universo. En este programa en vivo de “Obsesión por el Cielo” Edgar y Pedro platican en general sobre las teorías cosmológicas y sus evidencias. En la primera parte del programa resumimos la Teoría del Big Bang (La Gran Explosión) que es, hasta la fecha, el modelo que mejor explica las evidencias observacionales que tenemos. Esta teoría postula que el Universo entero (espacio, tiempo, materia, energía, fuerzas de la naturaleza, etc.) se creó hace unos 13,750 millones de años en una gran “explosión”. Las principales evidencias que apoyan esta teoría son la abundancia relativa de los elementos ligeros (hidrógeno, deuterio, helio), la expansión del Universo, y el Fondo de Radiación Cósmica en longitudes de onda de microondas. En la segunda parte del programa comentamos sobre otras teorías que históricamente han competido con el Big Bang. En particular resaltamos la Teoría del Universo en Estado Estacionario que a mediados del siglo pasado estipulaba que la densidad de materia el en Universo se mantenía constante por la creación de materia en el medio intergaláctico. Eventualmente las evidencias no la apoyaron. Otras teorías que mencionamos son la de la “Luz Cansada” de Fritz Zwicky, la que postula la existencia de múltiples Universos (Multiversoso), la que dice que nuestro Universo puede ser el resultado de la formación de un hoyo negro en una cuarta dimensión, la Cosmología Cíclica Conformal de Penrose, y otras más. Además de nuestra sección semanal de noticias, ofrecemos también nuestra sección de “Los Premios de Obsesión por el Cielo” en donde presentamos los premios ‘Constelación’ y ‘Movimiento Retrógrado’ a las noticias astronómicas más y menos relevantes, respectivamente, del mes de febrero del 2020. Esperamos que disfruten del programa.

J. Brian Pitts (Cambridge) gives a talk in the colloquium "On the Split Between Gravity and Inertia in Different Spacetime Theories" at the 17th UK and European Meeting on the Foundations of Physics (29-31 July, 2013) titled "Inertia and the Conformal-Projective Decomposition for Nordström-Einstein-Fokker, Massive Scalar, Einstein, and Massive Spin 2 Gravities". Abstract: The Ehlers-Pirani-Schild (EPS) construction, which derives a metric tensor from a projective connection and a conformal metric density, has sometimes been thought to undermine the conventionality of geometry. It might be of renewed interest due to the appearance of the dynamical or constructivist ap- proach to space-time geometry of Brown and Pooley. Constructivism shares with conventionalism the modally cosmopolitan awareness of a multiplicity of options, not all so tidy as to fit a unique geometry, leaving the ‘true’ geometry ambiguous. An EPS-inspired decomposition is applied to Nordström-Einstein-Fokker (massless spin 0) scalar gravity and its belatedly studied cousin, massive spin 0, which agree on the geometry seen by matter (conformally flat). For mas- sive scalar gravity, the symmetry group of the whole theory is the Poincaré group of Minkowski geometry, not the 15-parameter conformal group as in Nordström-Einstein-Fokker. By focusing only on the matter action, the EPS construction fails to notice the key geometrical diferences between massless and massive spin 0 theories and hence fails to address key issues motivating conventionalist and constructivist positions. For both massless and massive scalar gravities, inertia has an absolute core but is modifiable invariantly by gravity. The decomposition is then applied to Einstein’s General Relativity (mass-less spin 2) and its recently revived cousin(s), massive spin 2 gravity(s). Similar issues to the spin 0 comparison arise prima facie, but complicated by gauge freedom (in both cases but for different reasons) as well as the greater number of fields.

We introduce hybrid solar cells with an architecture consisting of an electrodeposited ZnO nanorod array (NRA) coated with a conformal thin layer (< 50 nm) of organic polymer-fullerene blend and a quasi-conformal Ag top contact (Thin/NR). We have compared the performance of Thin/NR cells to conventional hybrid cells in which the same NRAs are completely filled with organic blend (Thick/NR). The Thin/NR design absorbs at least as much light as Thick/NR cells, while charge extraction is significantly enhanced due to the proximity of the electrodes, resulting in a higher current density per unit volume of blend and improved power conversion efficiency. The NRAs need not be periodic or aligned and hence can be made very simply.

Gary Gibbons. Conformal Symmetry and Scaling Limits of Black Holes

Fortin investigates the theoretical implications of scale without conformal invariance in quantum field theory, arguing that the RG flows of such theories correspond to recurrent behaviors, i.e. limit cycles or ergodicity. He also discusses the implications for the a-theorem and show how dilatation generators do generate dilatations. Finally, Fortin discusses well-behaved non-conformal scale-invariant examples.

The AdS/CFT correspondence relates bulk Einstein geometries to boundary conformal geometry. We show that bulk geometry can also be described in terms of conformal geometry. This description yields a solution generating algebra in the bulk that controls solutions to very general bulk boundary problems. Using this algebra we present a boundary conformal calculus for conformally compact manifolds.

Conformal field theory is intimately connected to the theory of vertex algebras and the geometry of Riemann surfaces. In this thesis a new algebro-geometric structure called global vertex algebra is defined on Riemann surfaces which is supposed to be a natural generalization of vertex algebras. In order to define this structure a formal calculus of fields on Riemann surfaces is constructed. The basic objects in vertex algebra theory are fields. They are defined as formal Laurent series with possibly infinite principal part. The coefficients are endomorphisms. As an example for such a structure the global vertex algebra of bosons of Krichever-Novikov type will be constructed. At the beginning of this thesis the formal calculus of classical vertex algebras is introduced from the viewpoint of distributions in complex analysis. Furthermore a graphical calculus for the computation of correlation functions of primary fields associated to affine Kac-Moody algebras is introduced.

Background: The standard therapy for patients with clinically resectable rectal cancer is generally considered to be surgery, If the patient is diagnosed with advanced disease, postoperative radiochemotherapy (RCT) is usually recommended. In our study we aimed to investigate and analyze the effectiveness and toxicity of preoperative pelvic radiotherapy in combination with 5-fluorouracil (5-FU) in locally advanced rectal cancer. Patients and Methods: From June 1999 to September 2001 we evaluated 50 consecutive patients {[}37 male and 13 female; average age 65.1 (range 46-79.5) years] with locally advanced rectal carcinoma. 32 patients were staged as uT3, 14 as uT4, and 4 as uT2. Regarding N-staging, 22 patients were diagnosed as ONO. 2 patients had distant metastases, with liver metastases in both instances. Conformal irradiation was performed with a box technique 4-field technique) with a dose of 45 Gy (5 x 1.8 Gy per week for a total of 25 sessions). From days 1-5 and 29-33, all patients received 5-FU (500 mg/m(2) per day, as a continuous i.v. injection). Results: Remission was observed in 28 patients (56%), with down-staging of at least one T-stage. A better success rate was achieved for patients with deep-seated tumors (64% of the patients in this group). Complete remission was observed in 4 patients (8.0%) and progression in 3 (6.0%). 15 patients had no detectable change in tumor staging (30.0%). A surgical R0 resection could be achieved in 43 patients, an R1 resection (minimal margins in 7. Side effects and toxicity (common toxicity criteria) of RCT included grade I-II dysuria in 5 patients (10%), grade I-II diarrhea in 20 patients (40%), and severe diarrhea in 2 patients (4.0%). Grade I-II skin reaction was noticed in 22 patients (44.0%), severe skin reaction only in 1 patient. Regarding acute postoperative morbidity, abscess and fistula formation was noted in 8 patients (16.0%), with anastomosis leakage in 7 (14%). Conclusion: Preoperative radiotherapy appears to be a feasible therapeutic approach with moderate toxicity and the potential to induce down-staging. The data presented in this study confirm the preliminary reports on this neoadjuvant treatment.
