Re: Entanglement spectrum by charge (specifically for iDMRG)

For completeness I just wanted to add that this information has been used in my recent paper "Symmetry protected topological phases beyond groups: The q-deformed bilinear-biquadratic spin chain" ( 2011.12679 ) to compute a q-deformed version of the entanglement spectrum. In case anyone is ...

Re: Entanglement spectrum by charge (specifically for iDMRG)

Thank you very much for your detailed answer, Johannes, and apologies for the late reply. I agree that the charge offset is a gauge choice from the perspective of U(1)/S^z conservation. However, it is not from the perspective of full su(2) conservation since the number of states with S^z-charge m ne...

Entanglement spectrum by charge (specifically for iDMRG)

Dear TeNPy community, in order to get some intuition for how TeNPy works I have implemented the AKLT model and verified that the numerical DMRG results for string order, entanglement entropy and entanglement spectrum match the theoretical predictions (so far so trivial...). I have a question/comment...
