Chiral symmetry breaking in the pseudo-quantum electrodynamics with non-Abelian four-fermion interactions
Qiao Yang, Yu-Biao Wu, Wu-Ming Liu
In the context of 2+1 dimensional Dirac materials, we consider electromagnetic interactions alongside a type of spin-dependent Hubbard interaction. The former is described by PQED…
