Dynamical mean-field approach to disordered interacting systems and applications to quantum transport problem
Jiawei Yan, Philipp Werner
We discuss a non-equilibrium dynamical mean-field framework for simulating inhomogeneous Hubbard models with local disorders. Our approach treats electron interactions and disorder…
Failure of the mean-field description of magnetic fluctuations in the superconducting quantum dot
Václav Janiš, Jiawei Yan
The zero-temperature physics of interacting quantum dots attached to superconducting leads is now well understood. The overall qualitative picture is obtained from the static mean-…
Single impurity Anderson model out of equilibrium: A two-particle semi-analytic approach
Jiawei Yan, Václav Janiš
We apply a two-particle semi-analytic approach to a single Anderson impurity attached to two biased metallic leads. The theory is based on reduced parquet equations justified in cr…
Many-body perturbation theory for the superconducting quantum dot: Fundamental role of the magnetic field
Václav Janiš, Jiawei Yan
We develop the general many-body perturbation theory for a superconducting quantum dot represented by a single-impurity Anderson model attached to superconducting leads. We build o…
Antiferromagnetic fluctuations in the one-dimensional Hubbard model
Václav Janiš, Antonín Klíč, Jiawei Yan
We study the low-temperature critical behavior of the one-dimensional Hubbard model near half filling caused by enhanced antiferromagnetic fluctuations. We use a mean-field-type ap…
Curie-Weiss susceptibility in strongly correlated electron systems
Václav Janiš, Antonín Klíč, Jiawei Yan +1
The genesis of the Curie-Weiss magnetic response observed in most transition metals that are Fermi liquids at low temperatures has been an enigma for decades and has not yet been f…
