Pairing and charge order in a strongly-interacting Weyl system: Numerically exact results from auxiliary-field quantum Monte Carlo

ORAL

Abstract

The recent discovery of Weyl semimetals has generated intense interest in their properties. These materials have been predicted to exhibit a number of fascinating behaviors, including topological superconductivity. Here we study a model Weyl system subject to strong interactions using the numerically exact auxiliary-field quantum Monte Carlo technique. We focus on charge and pairing properties, in order to explore the interplay of Weyl physics, charge order, and superconductivity. These high-accuracy results will complement ongoing experimental efforts in Weyl systems, and help guide the search for exotic pairing phenomena in these systems, which can be realized in both real materials and ultra-cold atoms.
