Dear Jose,
I would like to report an inconsistency between results obtained for the ground-state energy of a four-site cluster Hubbard chain using dmrgpy and Itensor.jl. The Hubbard model includes …

Hello,
we are working on an extended Hilbert space in order to calculate the ground state energy of the Bose-Hubbard model. We added spin 1/2 sites between every boson site in the one-dimensional ch…

Hello, `quilc` wizards! I've caused an interesting crash on ARM64.
In order to get `quilc` to compile on ARM64, I had to [hack on `cffi` a little bit](https://github.com/cffi/cffi/issues/334), so p…

When debugging `tests/li_solv` I noticed that no information about the `Environment` is printed to the stdout output file, so it is impossible to deduce that the calculation is performed in an implici…

Hi, now I can successfully execute the code.
I want to know, how can I put statistical error for sampling?
I think there are two sources, one is for p and another is from quantum part.
What values …

Hi Jose,
This is an amazing package and I have made it a point to let all my collaborators know about it. Kudos for making such nicely constructed !! I have a couple of questions which are appended …

'chi_list' is designed for gradually growing the bond dimension.
In the comment of the code, it appears that 'chi_list' should be working for both 2-site and 1-site DMRG.
Growing bond dimension is s…
