Abstract

We theoretically study the stability of a Weyl semimetal against strong long-range Coulomb interactions. We consider a lattice model for a time-reversal symmetry broken Weylsemimetal with two nodes, and take into account the 1/r Coulomb interactions between the bulk electrons. Based on the U(1) lattice gauge theory, we investigate the system from the strong coupling limit. It is shown that spatial inversion (parity) symmetry of the system is spontaneously broken in the strong coupling limit, and a Weylsemimetal with broken time- reversal and inversion symmetries, which is different from the noninteractingone, survives in the strong coupling limit.
