Finite temperature effective action in monopole background

Gerald Dunne, Joshua Feinberg

Research output: Contribution to journalArticlepeer-review


We compute the CP-odd part of the finite temperature effective action for massive Dirac fermions in the presence of a Dirac monopole. We confirm that the induced charge is temperature dependent, and in the effective action we find an infinite series of CP-violating terms that generalize the familiar zero temperature FF term. These results are analogous to recent results concerning finite temperature induced Chern-Simons terms. (C) 2000 Elsevier Science B.V.
