simple-DMRG-with-MPS

Basic and simple module to run the density matrix renormalization group algorithm (DMRG) for matrix product states (MPS).

The main file is the DMRG_functionalities.ipynb that explains the algorithm and functions in DMRG.py.

DMRG_Ising.ipynb creates the phase diagram of the 1D transverse field Ising model.

This is inspired from TeNPy (https://github.com/tenpy/tenpy)
