Reliable simulations of correlated quantum systems, including high-temperature
superconductors and frustrated magnets, are increasingly desired nowadays to further our …

Despite rapidly growing interest in harnessing machine learning in the study of quantum
many-body systems, training neural networks to identify quantum phases is a nontrivial …

A fundamental open issue in physics is whether and how the fermion sign problem in
quantum Monte Carlo (QMC) simulations can be solved generically. Here, we show that …

We review recent developments regarding the quantum dynamics and many-body physics
with light, in superconducting circuits and Josephson analogues, by analogy with atomic …

Topological insulators present a bulk gap, but allow for dissipationless spin transport along
the edges. These exotic states are characterized by the Z2 topological invariant and are …

It is expected that the interplay between nontrivial band topology and strong electron
correlation will lead to very rich physics. Thus a controlled study of the competition between …

Weyl semimetals (WSMs) constitute a 3D phase with linearly dispersing Weyl excitations at
low energy, which lead to unusual electrodynamic responses and open Fermi arcs on …

In a recent article, Grover [Phys. Rev. Lett. 111, 130402 (2013) PRLTAO 0031-9007
10.1103/PhysRevLett. 111.130402] introduced a simple method to compute Renyi …

The existence of degenerate or gapless edge states is a characteristic feature of topological
insulators, but is difficult to detect in the presence of interactions. We propose a new method …

We investigate the role of short-ranged electron-electron interactions in a paradigmatic
model of three-dimensional topological insulators, using dynamical mean-field theory and …
