The charge-*q* Schwinger model is the *(1+1)*-dimensional quantum electrodynamics (QED) with a charge-*q* Dirac fermion. It has the *\mathbb{Z}_q* *1*-form symmetry and also enjoys the *\mathbb{Z}_q* chiral symmetry in the chiral limit, and there is a mixed 't Hooft anomaly between those symmetries. We numerically study the charge-*q* Schwinger model... Show more
