Quantum Properties of Periodic Instantons on a Circle

High Energy Physics - Theory 2011-02-11 v3

Abstract

Quantum properties of a (1+1)-dimensional scalar theory on a cylinder with a compact spatial part, namely, 0xL0\leq x\leq L, are considered. In particular, quantum theory around the classical periodic field configurations is studied and the lifetime of a quantum periodic instanton is estimated.
