Abstract:

We apply the method of collective coordinate to get a well-defined expression of finite temperature partition function suitable for calculation of free energy of a classical solution. It yields zero-mode factor in unambiguous way and gives a basis for systematic expansion, which will be used to estimate transition rate of topological number through sphaleron configuration.
