XXZChain antiferromagnet showing no entanglement?
Hi, I just started using TeNPy. I was trying to simulate the XXZChain in Google Colab with parameters, Jxx = 1. , Jz = 2., hz = 0 with tebd.Engine but it keeps giving back zero in the entanglement_spectrum. Here is my code: tebd_params = {'order': 2, 'delta_tau_list': [0.1, 0.001, 1.e-5], 'max_error...
