Implementing iDMRG for ladder lattices
Dear Johannes, I hope you are doing great. We met at the DPG meeting this year (I recognized you in a talk, went to yours, and asked you about time evolution for open systems). I am writing now because I am trying to implement an iDMRG code on a ladder system. My code is huge, but I'll try to point ...

Re: Implementing TEBD of open quantum chain in TenPy.
Hi,
Will there be a future realease with options for Lindblad evolution? I am very interested of what was the result of this discussion.
Best regards,
F. P. M. Méndez-Córdoba

Re: How to efficiently save and resume calculation
Hi there, I wasn't able to make this work. Do you have an example code of the usage of the checkpoints?

Problems with add_local_term and H.c
Hi, I'm trying to decrease the number of terms appearing in the Hamiltonian MPO by using H. c. in add_coupling_term. However, when I use plus_hc I always get an error. I have tried this with different models, and I get the same error. I provide an example below. I have a ladder of SpinHalfFermions o...

Question about the Hamiltonian MPO
Hi, thanks a lot for creating these libraries. I love the simplicity of constructing DMRG codes with them! I have a question, why do the first Hamiltonian MPO sites always have two rows instead of one? I have worked with the TNT libraries, and we use 1 row and 1 column at the first and last sites in...
