Description
In numerical calculation of the lattice QCD, the sign problem of Monte Carlo methods has been a major issue.
A numerical renormalization group called tensor renormalization group (TRG) is one of the candidates for the solution of this problem.
Grassmann tensor renormalization group (GTRG) is a generalization of the TRG to fermion systems.
In this study, We apply the GTRG to the lattice Gross-Neveu model in the presence of a chemical potential as a benchmark for future works in finite density systems.
