QED With Unequal Charges: A study of spontaneous Zn symmetry breaking
arXiv:hep-ph/9405324 · doi:10.1016/0550-3213(95)00360-5
Abstract
We study two-dimensional QED with unequal charges at finite temperature, and show that there is a phase with a spontaneously broken $Z_n$ symmetry. In spite of this, we were not able to establish the presence of domain walls. The relevance for QCD in higher dimensions is discussed.
