Non-hermitian Matrices

Hi, all

Can TeNPy be used to deal with non-hermitian matrices? I see this issue https://github.com/tenpy/tenpy/issues/96 but I am not sure about the current status. Does TEBD work now? How about DMRG? If it helps, the eigenvalues of the matrices that I want to deal with are all real.

Re: About calculating the momentum for entanglement spectrum

Thank you very much for your kind reply! Reference 2 is indeed a very good reference :D And I like the idea of the forum very much as well However, I indeed do not find that the entanglement spectrum works (as I suspected) for kagome lattice. For Ly = 4 I get 2.337148476855845 as entanglement entrop...

About calculating the momentum for entanglement spectrum

Hi, all! I have posted an issue on the github and then found this forum. I think it may help to ask it here as well. I am using the package to do some dmrg calculation in 2D and I need to calculate the momentum for entanglement spectrum. However, I find the entanglement spectrum I get from the funct...
