Description
The Wilson fermion determinant can be written in the form of a series
expansion in fugacity z=exp(mu/T), provided that the eigenmodes of the
temporally reduced operator are obtained. Since the calculation of
all eigenmodes rapidly becomes prohibitive for larger volumes, we
develop a method to calculate only the low-energy eigenmodes of the
reduced matrix using a matrix filetering technique. This provides a
basis of an approximation to neglect uninteresting ultraviolet contributions.
