Orientational ordering of water molecules confined in beryl: A theoretical study
Antonín Klíč, Václav Janiš, Filip Kadlec
We present an improved model for studying the interactions between dipole moments of water molecules confined in beryl crystals, inspired by recent NMR experiments. Our model is ba…
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…
Quantum diffusion in a random potential: A consistent perturbation theory
V. Janiš, J. Kolorenč
We scrutinize the diagrammatic perturbation theory of noninteracting electrons in a random potential with the aim to accomplish a consistent comprehensive theory of quantum diffusi…
