total error while time evolving the state

Dear Tenpy Developer, I am using tenpy for obtaining Finite temperature state with purification tool and then evaluating some local two site quantity from that finite temperature state. I wanted to know how much error I have accumulated while carrying out this imaginary time evolution along with tru...

Re: [RESOLVED] Issue in purification method (normalization of temperature and/or timescales?)

Hi Since you tried this method, I had a question. I was playing around on this purification method by implementing it on Kitaev model. I tried to evaluate the flux expectation values at different beta ranging from zero to lets say 30. Using Exact diagonalization, I see flux value reaches one(it shou...

code issue TFI2D model implementation

Hi I am new to tenpy package and tried to evaluate in 2D transverse field ising model and implemented code is here. But i am getting bug in this code. Can someone help me to fix the bug. Thanks import numpy as np from tenpy.networks.mps import MPS from tenpy.algorithms import dmrg from tenpy.models....
