Maybe this is already quite late but are you able to obtain the ground state using iDMRG in canonical form? I expect that iDMRG cannot just converge at the critical point since it corresponds to a gapless state and thus cannot be expressed by an iMPS of finite dimension. I think that you are able to...

I am studying a problem where I have a three site unit cell consisting of two fermion sites and one bosonic site. I am interested in calculating the eigenvalues of the generalised transfer matrix to check whether the obtained ground state (using iDMRG) is symmetric under a given symmetry and to even...

Thanks a lot for your reply.
I took into account the lower part of the entanglement spectrum and obtained convincing results

I am studying a model with iDMRG and was wondering if I can extract correlation functions using iDMRG? I am interested in studying the possibility of a superconducting phase by studying the correlators. My initial lattice size is 2 (before iDMRG run). Also, is it possible to extract central charge u...

Hi, I am using iDMRG to calculate the entanglement spectrum of my model. Our model consists of three site unit cells with two sites being spin-half fermionic and one bosonic. My aim is to find the degeneracies in the entanglement spectrum to confirm our analytical calculation of the existence of an ...
