ITensors.jl
A Julia library for efficient tensor computations and tensor network
...It enables efficient manipulation of large, structured tensors with named indices and provides an intuitive interface for implementing algorithms like DMRG (Density Matrix Renormalization Group), TEBD (Time-Evolving Block Decimation), and more. ITensors.jl leverages Julia’s multiple dispatch and performance features to simplify the development of scalable and complex simulations involving quantum many-body systems.
