A formally exact one-frequency-only Bethe-Salpeter-like equation. Similarities and differences between GW +BSE and self-consistent RPA
Valerio Olevano, Julien Toulouse, Peter Schuck
A formally exact Bethe-Salpeter-like equation for the linear-response function is introduced with a kernel which depends only on the one frequency of the applied field. This is in…
Two-dimensional Mixture of Dipolar Fermions: Equation of State and Magnetic Phases
Tommaso Comparin, Raul Bombin, Markus Holzmann +3
We study a two-component mixture of fermionic dipoles in two dimensions at zero temperature, interacting via a purely repulsive potential. This model can be realized with u…
Comparison of cuprates and nuclear matter pairing properties. Quartet (alpha-particle) condensation in nuclear systems
P. Schuck
A comparison of pairing properties in cuprates and nuclear matter is briefly discussed. Quartet (alpha-particle) condensation is a very important aspect of nuclear physics. The phy…
Signature of the transition to a bound state in thermoelectric quantum transport
Étienne Jussiau, Masahiro Hasegawa, Robert S. Whitney
We study a quantum dot coupled to two semiconducting reservoirs, when the dot level and the electrochemical potential are both close to a band edge in the reservoirs. This is model…
Limites de champ moyen bosoniques {à} temp{é}rature positive
Nicolas Rougerie
I present recent results in quantum statistical mechanics, obtained in joint works with Mathieu Lewin and Phan Th{à}nh Nam. We consider a certain mean-field limit of the grand-cano…
Non-equilibrium System as a Demon
Rafael Sánchez, Janine Splettstoesser, Robert S. Whitney
Maxwell demons are creatures that are imagined to be able to reduce the entropy of a system without performing any work on it. Conventionally, such a Maxwell demon's intricate acti…
