Internodal excitonic state in a Weyl semimetal in a strong magnetic field

René Côté, Gautier D. Duchesne, Santiago F. Lopez

The simplest Weyl semimetal with broken time-reversal symmetry consists of a pair of Weyl nodes located at wave vectors ${\mathbf{K}}_{\tau }=\tau \mathbf{b}$ in momentum space with $τ=\pm 1…
