Tensor renormalization group study of (3+1)-dimensional ℤ2 gauge-Higgs model at finite density
We investigate the critical endpoints of the (3+1)-dimensional ℤ2 gauge-Higgs model at finite density together with the (2+1)-dimensional one at zero density as a benchmark using the tensor renormalization group method.
