Monopole charge density wave states in Weyl semimetals

Year: 2020

Type: article

Abstract: This work proposes a topological class of density wave order that cannot be described by spherical harmonic symmetry but is characterized by monopole harmonics. This order, termed monopole density wave order, is demonstrated in a Weyl semimetal model where electron and hole Fermi surfaces with different Chern numbers are nested so that the density wave order acquires a nontrivial pair Berry phase.
