Detailed Description

template<typename AFIELD>
class AFopr_Wilson_Chemical< AFIELD >

Wilson fermion operator with chemical potential.

This class implements the Wilson fermion operator at finite chemical potential. Former Fopr_Wilson_Isochemical class was converted to a template class and renamed. The first version was implemented by H.M. [22 Aug 2012] and has been improved by Y.Namekawa and H.M. [27 Feb 2022 H.Matsufuru]
