Content

We have developed Grassmann higher order tensor renormalization group (GHOTRG) to analyze higher dimensional fermionic systems. We first apply it to three-dimensional free Wilson fermions as a benchmark to check its effectiveness. The results of the free energy and the fermion Green functions are presented in comparison with the exact values. We also briefly discuss to what extent the results are improved by Grassmann higher order second renormalization group (GHOSRG).
