Fermi-Bose mixtures and BCS-BEC crossover in high-Tc superconductors
, 2019 In this review article we consider theoretically and give experimental support to the models of the Fermi-Bose mixtures and the BCS-BEC crossover compared with the strong-coupling approach, which can serve as the cornerstones on the way from high ...

Mean-field solution of the Hubbard model: the magnetic phase diagram
, 2014 The present paper is based on our graduate lectures in condensed-matter physics. We found that the mean-field solution of the Hubbard model is an excellent tool to stimulate students' reflections towards the treatment of realistic magnetic interactions ...

Ultrabroadband time-resolved spectroscopy in novel types of condensed matter
, 2016 In condensed matter physics, quasi-particle correlations are crucial to understanding a material’s properties. For example, strong interaction between electrons with metal-like electron configuration produces strongly correlated insulators rather than ...

Breakdown of traditional many-body theories for correlated electrons
, 2017 Starting from the (Hubbard) model of an atom, we demonstrate that the uniqueness of the mapping from the interacting to the noninteracting Green's function, $G\to G_0$, is strongly violated, by providing numerous explicit examples of different $G_0 ...

Nonlocal correlations induced by Hund's coupling: a cluster DMFT study
, 2015 We study spatial correlation effects in multiorbital systems, especially in a paramagnetic metallic state subject to Hund's coupling. We apply a cluster extension of the dynamical mean-field theory (DMFT) to the three-orbital Hubbard model away from half

, 2015 Interacting Bose-Fermi systems play a central role in condensed matter physics. Here, we analyze a novel Bose-Fermi mixture formed by a cavity exciton-polariton condensate interacting with a two-dimensional electron system.

A new form of (unexpected) Dirac fermions in the strongly-correlated cerium monopnictides
, 2016 Discovering Dirac fermions with novel properties has become an important front in condensed matter and materials sciences. Here, we report the observation of unusual Dirac fermion states in a strongly-correlated electron setting, which are uniquely ...
