We assess the accuracy of ghost-rotationally-invariant slave-boson (g-RISB) theory in
multiorbital systems by applying it to both the three-orbital degenerate Hubbard model and a …

It has been reported that upon do** a Mott insulator, there can be a crossover to a
pseudogapped metallic phase followed by a first-order transition to another …

We investigate the metal-to-insulator phase transition driven by the density-density
electronic interaction in the quarter-filled model on a cubic lattice with two orbitals split by a …

Identifying phase boundaries of interacting systems is one of the key steps to understanding
quantum many-body models. The development of various numerical and analytical methods …

We show how the stability conditions for a system of interacting fermions that conventionally
involve variations of thermodynamic potentials can be rewritten in terms of one-and two …

Creating heterostructures with graphene/graphite is a practical method for charge-do** α-
RuCl 3, but not sufficient to cause the insulator-to-metal transition. In this study, detailed …

In recent years, the $ T $-linear scattering rate found at low temperatures, defining the
strange metal phase of cuprates, has been a subject of interest. Since a wide range of …

We introduce the generalization of the slave-spin mean-field method to broken-symmetry
phases. Through a variational approach we derive the single-particle energy shift in the …

Quantum materials featuring both itinerant and localized degrees of freedom exhibit
numerous exotic phases and transitions that deviate from the Ginzburg-Landau paradigm …
