Yet another matrix product state (MPS) implementation, written in Julia

JuMPS

Yet another matrix product state (MPS) implementation, written in Julia.

Usage

Install julia, version > 1.0 and the packages Arpack, TensorOperations, LinearMaps. Then, in the Julia REPL:

include("../path/to/JuMPS.jl")
using .JuMPS

The first run will be slow, since Julia compiles the functions.

Roadmap

• model -> MPOs
• exact diagonalization
• MPS
  • left-/right-orthogonalization
  • use svds when possible
  • factorize: multiple-dispatch used for different MPS types
  • symmetric MPS
• infinite DMRG
• finite DMRG
• infinite TEBD
• finite TEBD
• infinite TDVP
• finite TDVP
• transfer matrices
  • canonicalization
  • correlation length
  • moments
