Instantons in quark plasmas. Role of zeroth fermion modes
Abrikosov A.A. Jr.
The single-loop increment in the action of an instanton in a plasma of light quarks is calculated by the method of exact Green's functions. Off-diagonal elements of the particle density matrix are taken into account. A temperature-independent term, which suppresses large instantons, is found.
