That’s great to hear, Valentin. May we request a new topic called “Tensor Networks” ?
We were considering directing our users to the Quantum category (or maybe the Numerics category), but tensor networks are their own area of specialized knowledge and are being explored heavily not only for quantum physics, but for machine learning, PDE solving, and so on. Julia already has at least two tensor network packages (ITensor and TensorKit, and you might count TensorOperations too).
We could discuss more if the forum mods are open to this. Maybe it would be better to have the category also include low-rank methods such as hierarchical matrices too.
