Winding expansion techniques for lattice QCD with chemical potential
Winding expansion techniques for lattice QCD with chemical potential
We analytically derive a decomposition of the lattice fermion determinant for Wilson's Dirac operator with chemical potential into winding sectors, i.e., factors with a fixed number of quarks. Dividing the lattice into four domains, the determinant is factorized into terms which can be classified with respect to the winding number …
