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: itensor.discourse.group/t/ann-initial-…

Why do some parts of ITensors.jl have type instabilities and use dynamic dispatch, and does this hurt performance? A good answer by Matt Fishman to this question: itensor.discourse.group/t/dynamic-disp…

Our DMRG study of the quantum critical point in 1D water is published @PhysRevLett. This work wouldn't be possible without the incredible @ITensorLib software. Also, don't miss the fantastic Viewpoint by Marivi Fernández-Serra @Perimeter @UWaterloo journals.aps.org/prl/abstract/1…

Two weeks ago I finished my internship at @FlatironCCQ working on the superconducting properties of the t-t’ Hubbard model using @ITensorLib. A great experience in a great place, where I got to meet brilliant researchers and make a lot of friends. Hope to be back soon!

The ITensor Paper is published! Nice to see other leading software efforts e.g. @NetKetOrg) also publishing in SciPost Codebases

If you're using a new M-series Mac, the new Julia 1.8 is a good time to upgrade to the ARM version of Julia. ITensor DMRG (1D Hubbard model) is **twice as fast** as Julia 1.7 running in Rosetta (Intel emulation) mode.
