ITensor has a paper! We lay out the philosophy behind ITensor and give lots of examples of the key parts of the interface (mostly in Julia). We also discuss some advanced features, NDTensors.jl, and some future plans.
ITensor
@ITensorLib
Software for tensor networks inspired by tensor diagrams, in Julia and C++. Supported by the Flatiron Institute, a division of the Simons Foundation.
- Example model 1D system showing a beyond-group symmetry studied with ITensor DMRG. "Non-invertible symmetry-protected topological order in a group-based cluster state" Christopher Fechisin, Nathanan Tantivasadakarn, Victor V. Albert.
- Our new ITensor GPU backend system is now live in the latest Julia version, building on hard work by Karl Pierce and Matt Fishman, using the elegant new package extension system. See Matt's post about the initial release here:
- Exciting update on what’s new in Julia. Very informative thread:#JuliaCon final day! The keynote is the State of Julia talk, my favorite one each year :)
- Beautiful agreement between numerics (DMRG based on ITensor) and Ginzburg-Landau theory calculations of coexistence of CDW and superconductivity in t-t'-U Hubbard model.
