The EE is different for different initial setup
Hi, all, I am trying to implement a heisenberg chain with alternating bond strength. I am implementing using XXZ model from tenpy. However, when I try to calculate the entanglement entropy(EE), the result is different for different initial setup. Any suggestions here? Thank you so much! Here is my c...

Why does my SSH model not working
I am trying to code the SSH model using tenpy, but it looks like the product state got some problems, which I am confused about, here are my codes and the error def example_DMRG_SSH_infinite_S_xi_scaling(): L = 50 # or whatever you like... t1, t2 = 0.5, 1.5 t_array = np.array([(t1 if i % 2 == 0 else...

Newcomer of tenpy having an issue with my code
I have written a code in tenpy to simulate the 1D heisenberg chain, but it looks like finally my code does not create any "dynamic properties" at all(Both my energy and my entanglement entropy does not change at all). Can anyone help me with that? Thank you guys so much!Attached are my cod...
