The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

In this work, we present an overview of the phaseless auxiliary-field quantum Monte Carlo
(ph-AFQMC) approach from a computational quantum chemistry perspective and present a …

Platinum-based transition metal dichalcogenides have been gaining renewed interest
because of the development of a new method to synthesize thin film structures. Here, using …

A spin liquid is a novel quantum state of matter with no conventional order parameter where
a finite charge gap exists even though the band theory would predict metallic behavior …

We have investigated the effects of doping on a single layer of graphene using angle-
resolved photoemission spectroscopy. We show that many-body interactions severely warp …

The effect of Lifshitz transition on thermodynamics and superconductivity in hole-doped
cuprates has been heavily debated but remains an open question. In particular, an observed …

We derive a differential equation for the one-particle-irreducible vertex functions of
interacting fermions as a function of the temperature. Formally, these equations correspond …

We use a novel temperature-flow renormalization group technique to analyze magnetic and
superconducting instabilities in the two-dimensional t− t′ Hubbard model for particle …

We explore different ways of incorporating accurate trial wave functions into free projection
auxiliary-field quantum Monte Carlo (fp-AFQMC). States employed include coupled-cluster …

We consider the ground-state magnetic phase diagram of the two-dimensional Hubbard
model with nearest-and next-nearest-neighbor hopping in terms of electronic density and …
