Code for Khindanov et al., Robust Preparation of Ground State Phases Under Noisy Imaginary Time Evolution.
The DMRG code uses ITensors.jl package and can be utilized to compute ground states, Binder cumulants, energy gaps, correlation functions, and state fidelities for the Ising spin ladder models with various inter-leg couplings.
The direct density matrix simulation uses CuPy package for GPU-accelarated computing.
