Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

We consider the nanoscale electronic phase separation in a wide class of different
materials, mostly in strongly correlated electron systems. The phase separation turns out to …

Phase separation plays a central role in the emergence of unusual functionalities of
correlated electron materials. The structure of the mixed-phase states depends strongly on …

Disorder or sufficiently strong interactions can render a metallic state unstable, causing it to
turn into an insulating one. Despite the fact that the interplay of these two routes to a …

Recently, the learning by confusion (LbC) approach has been proposed as a machine
learning tool to determine the critical temperature T c of phase transitions without any prior …

The two-dimensional Falicov-Kimball (FK) model is analyzed using the Monte Carlo method.
In the case of concentrations of both itinerant and localized particles equal to 0.5 we …

The phase diagram for doped manganites and related compounds is analyzed in terms of
the Kondo-lattice model taking into account an interplay between electrons localized due to …

The two-band Hubbard model is used to analyze a possibility of a nonuniform charge
distribution in a strongly correlated electron system with two types of charge carriers. It is …

In this paper we introduce an exactly solvable Kondo lattice model without any fine-tuning
local gauge symmetry. This model describes itinerant electrons interplaying with a localized …

Luttinger's theorem has long been taken as the key feature of Landau's Fermi liquid, which
signals the presence of quasiparticles. Here, by the unbiased Monte Carlo method, violation …
