On January 20th, 1971 in private negotiation, Low and Frutkin met with Keldysh and Feoktistov to discuss rendezvous and docking. NASA proposed developing compatible systems for Apollo and Soyuz rather than future spacecraft, aiming to give specialists something concrete on … Continue reading → The post Space Rocket History #447 – Apollo-Soyuz Test Project – Creating a Partnership first appeared on Space Rocket History Podcast.

Join me for a frank, inspiring and oft-hilarious conversation with Fran Capo--a writer, a comedian, a world record holder and life-long adventurer who has literally been to the top of the world and to the bottom of the sea. Her visit to Titanic on board the Keldysh had me, and will have you, enamored: we speak about her time on the research vessel (with Anatoly!), her experience at the shipwreck site, and how much a history-making journey like this has meant in her life. We also discuss her Ted Talk, the gorgeous whirlwind of a "yes" mindset, and how she's opened her life to pure adventure.Find her website/contact Fran here: https://francapo.comSupport the showSupport Unsinkable on Patreon: https://podcasts.apple.com/us/podcast/unsinkable-the-titanic-podcast/id1585578882Support the pod by buying Titanic-related books through my Bookshop Storefront: https://bookshop.org/shop/unsinkablepodFind me on Instagram: https://www.instagram.com/unsinkablepod/Shoot me an email if you like: UnsinkablePod@gmail.com

Sean is joined by Alexia from Titanic Talkline to review the Titanic documentary Ghosts of the Abyss (2003), which documents James Cameron's 2001 expedition. This was his first journey back to the Titanic wreck since 1995, when he shot footage for his Titanic (1997) motion picture. This episode is accessible for both those who are familiar with Titanic history and those who may know less about the shipwreck, as both Alexia and Sean do their upmost to explain the documentary as fully as they can. Sean scuppers the discussion partway through with a very distracting mug. Discussion Points: -Beloved and lost treasure Bill Paxton. -The main players in the documentary and how it was very much a family affair. -The unseen troubles which befell the expedition, which is not shown in the documentary film but is documented in the book. -How dangerous it is just to live on the boat. -Visual Navigational Aids-what they are and how they are critical to explore the wreck safely. -Sean's theory as to why memorial plaques are left on the stern rather than the bow. -Alexia's surprisingly good English accent. Random Questions: -How many times does Sean tell everyone he's read the book? -Do a lot of Titanic documentaries skip how difficult and dangerous it is to dive to the wreck? -Whilst on-board the Keldysh, what did Bill Paxton get told off by a Russian crewmember for? -Does the resolution of older images of the Titanic wreck compared with the most recent 8k footage (during the Ocean Gate in 2022) of Titanic make the deterioration of the wreck look worse? -Did you know Titanic movie parody merchandise exists? (Sean didn't). Random Quotes: -"If you haven't already tuned out". -"Unless you get a really benevolent squid, you're screwed"-"Good segway, there's a biologist on board". -"The front of the ship, the bow, is really romanticised, obviously the film helps...it looks kind of like normal...but then you look at the stern of the ship and it's like a death you've never experienced". -"Diving to the ship takes more from you than it will ever give". Correction: The lifeboat lowering is from the documentary Titanic: 20 Years Later with James Cameron. Disclaimer-It is disputed as to what happened to Bob Ballard's 1986 expedition plaque, some claim it was stolen, whilst others think it slipped from it's original position and was covered by sediment. Alexia will return to take part in the Defend It Yourself series, to defend Showgirls. Thanks for listening!

We are back on the Keldysh and talk about a new contender for worst line and learn about Death's Door.

Rose arrives on the Keldysh, but can we trust what she says?

Brock and crew gather on deck. We learn more about the Keldysh and laws of the sea.

This thesis aims at shedding light on the microscopic origin of a phenomenon in the field of semiconductor nanostructures, which occurs in transport through a short and narrow quasi one-dimensional constriction, the quantum point contact (QPC). Unlike the stepwise increase of linear conductance of a QPC as function of its width in units of the quantum GQ, which is well understood and was predicted already in the 1950s, an additional shoulder-like step at 0.7xG_Q raises questions since its discovery in 1996 : the 0.7 anomaly. Subsequent experimental investigations revealed a plethora of accompanying features of this fascinating structure. Most famously these include a strong reduction of conductance in the sub-open regime of a QPC as function of external parameters such as magnetic field, temperature or bias voltage. While it is agreed upon that the 0,7 anomaly arises from electron-electron interactions, the high number of theoretical attempts at an explanation indicates that the detailed microscopic origin of the peculiar shoulder is still subject to controversal discussions. In particular no theory seems to describe the whole variety of signatures of the 0.7 anomaly sufficiently. Here, we present a microscopic model that qualifies to meet this requirement. We model the effective barrier of the lowest transport mode of a QPC by a one-dimensional parabolic potential with short-ranged Coulomb interactions. By systematic analysis of experimental data we show that a parabolic barrier approximates the actual barrier shape of the QPC adequately well. In order to understand the physics of a QPC in detail, we put emphasis on the noninteracting properties of our model; we find a pronounced maximum in the local density of states in the vicinity of the barrier center at energies just above the potential. Importantly, this "van Hove ridge", which can be associated with slow electrons above the barrier coincides with the chemical potential if the QPC is tuned to be sub-open. Here, it causes an enhancement of backscattering at finite interactions and a subsequent anomalous reduction of conductance. In case of a magnetic field the underlying mechanism for this reduction is an interaction-enhanced local depopulation of the disfavoured spin species' subband; at finite excitation energies the reduction is a consequence of an interaction-enhanced inelastic backstattering probability. Hence, the interplay of van Hove ridge and electron-electron interactions provides a natural explanation for the appearance of the 0.7 anomaly and its various features. We calculate properties of our interacting one-dimensional QPC model using two methods: A specially developed approximation scheme within the functional renormalization group (fRG) provides reliable results for the magnetic field dependence of the 0.7 anomaly at zero temperature. At finite temperature and finite bias voltage we rely on second order perturbation theory in the interaction (SOPT). Since SOPT's validity is restricted to weaker interaction strength, where calculations clearly show the right trend but not yet the full manifestation of the 0.7 anomaly, we are currently setting up an extension of our fRG approach within the Keldysh formalism, which will allow us to also explore finite excitation energies.

The study of the interplay between interaction-induced correlations and nonequilibrium initial conditions in many-body systems has recently attracted a lot of attention. New experimental techniques provide high control over many-body systems and systematic access to their nonequilibrium regime. In many systems the nonequilibrium properties of a Fermi liquid can be relevant. A first approach to their understanding is the main content of this thesis. At the beginning, nonequilibrium phenomena, Landau's theory of a Fermi liquid, the Hubbard model, time evolution in quantum mechanics, related experiments, and the flow equation method are reviewed. The key observation of this thesis, namely a characteristic mismatch of expectation values in equilibrium and nonequilibrium, is first illustrated for the squeezed oscillator. For this one-particle model Hamiltonian the perturbative approach can be compared with the exact solution and it is shown that the mismatch holds even beyond perturbation theory. Afterwards these observations are generalized to a larger class of one-particle models. Then the nonequilibrium behavior of a Fermi liquid is examined by analyzing the Fermi liquid phase of the Hubbard model in more than one dimension. After a sudden switch-on of a weak two-particle interaction to the noninteracting Fermi gas the relaxation of the many-body system is observed. For this purpose, the flow equation transformation is implemented for the Hubbard Hamiltonian. Then the discussion of the momentum distribution function and of the kinetic energy displays a three-step relaxation behavior of the Fermi liquid from the initial perturbation until thermalization is reached. Firstly, the sudden switch inserts excitation energy into the system which drives the following dynamics. Then a rapid initial build-up of correlations is caused by initial dephasing and leads to the establishment of a quasiparticle picture. By that the system enters into a quasi-stationary state which can be long-lasting for weak interaction. This state shows prethermalization of the kinetic energy which already has relaxed to its final values. However, the momentum distribution still resembles a zero temperature Fermi liquid. Its later relaxation on a second time scale is caused by a residual two-particle interaction which allows for scattering processes and can be described by a quantum Boltzmann equation. The physical origin of this delayed relaxation can be traced back to an interplay of translational invariance of the Hubbard model and the Pauli principle for fermions; together they restrict the phase space for scattering events. Comparing with similar work I conjecture on the generic nature of the findings made for the quenched Fermi liquid in other many-body systems. Finally I point out to the potential relevance of the delayed relaxation for the observation of further nonequilibrium phenomena, for instance in BCS systems. In order to extend the study of sudden switching to arbitrary switching processes the calculation is repeated using the Keldysh perturbation theory. First evaluations for a linear increase of the interaction strength are given. Extensions of this work are suggested and may motivate further research.
