DMRGPy is a Python library to compute quasi-one-dimensional spin chains and fermionic systems using matrix product states with DMRG as implemented in ITensor. Most of the computations can be performed both with DMRG and exact diagonalization for small systems, which allows one to benchmark the results.

Sample Example to Calculate the various Quantum Entanglement Measures at Zero T, Finite Temperature #24

Closed hcut closed 6 months ago

Hi Joselado,

I appreciate your library. It helps us in learning and understanding the spin systems.

I have a request for you.

I want to do some calculations on Quantum Entanglement Measures (Temperature dependent also) such as Concurrence. It would be be nice to see some sample example for 1D spin chain, It will great if you can add, suggest some piece of code for doing such calculations.

Thanks.

Hi hcut,

thanks for the message. Currently the code does not have implemented calculation of concurrence at finite temperature. This would be of course something that may be included in the future.

Best regards, Jose
