Questions about applying DMRG, other MPS algorithms, and general numerical methods based on tensor networks.
Please read the our guide to using the forum before posting, to make it easier for us to help you!
Please take a look at the DMRG FAQ in the ITensor documenation before asking questions about the convergence of DMRG calculations. Hopefully that will cover many questions you might have about the convergence of DMRG calculations, but if not please ask your questions in this category and we will be happy to answer them. If you find something missing or confusing in the FAQ, also please let us know and we can update it.
