Methods to discretize the Hamiltonian of a topological insulator or topological
superconductor, without giving up on the topological protection of the massless excitations …

Employing large-scale quantum Monte Carlo simulations, we systematically compute the
energy spectra of the two-dimensional (2D) spin-1/2 Heisenberg model with long-range …

In this work, building on state-of-the-art quantum Monte Carlo simulations, we perform
systematic finite-size scaling of both entanglement and participation entropies for long-range …

It is expected that the Gross-Neveu-Yukawa (GNY) chiral Ising transition of Dirac fermions
coupled with a scalar field in (2+ 1) dimensions will be the first fermionic quantum critical …

The Luttinger model is a paradigm for the breakdown due to interactions of the Fermi liquid
description of one-dimensional massless Dirac fermions. Attempts to discretize the model on …

We investigate a 2+ 1 D interacting Dirac semimetal with on-site flavor SU (2) symmetry.
Topological considerations imply that the skyrmions in the flavor-symmetry-breaking phase …

A fundamental concept in condensed matter physics is that the effective behavior of
electrons is strongly influenced by the medium in which they exist. An example of this is …
