For about 20 years, it has been the prevailing view that there can be no metallic state or
metal-insulator transition in two dimensions in zero magnetic field. In the last several years …

Systematic deviations from standard Fermi-liquid behaviour have been widely observed and
documented in several classes of strongly correlated metals. For many of these systems …

The “sign problem”(SP) is a fundamental limitation to simulations of strongly correlated
matter. It is often argued that the SP is not intrinsic to the physics of particular Hamiltonians …

We design a quantum battery made up of bosons or fermions in an ultracold-atom setup,
described by Fermi-Hubbard and Bose-Hubbard models, respectively. We compare the …

We study the transitions from band insulator to metal to Mott insulator in the ionic Hubbard
model on a two-dimensional square lattice using determinant quantum Monte Carlo …

We obtain the Seebeck coefficient or thermopower S, which determines the conversion
efficiency from thermal to electrical energy, for the two-dimensional Hubbard model on …

Motivated by the recently experimental reported signatures of the tunable Mott insulating
state and superconductivity in an ABC graphene trilayer superlattice, we investigate the …

The physics of semiconductors has seen an enormous evolution within the last? fty years.
Countless achievements have been made in scienti? c research and device applications …

We study the real-time dynamics of a two-dimensional Anderson-Hubbard model using
nonequilibrium self-consistent perturbation theory within the second-Born approximation …

We show that, with increasing randomness, the spectral gap in a 2D Mott-Hubbard insulator
is destroyed first at a disorder V c 1, while antiferromagnetism persists up to a higher V c 2 …
