Hi Miles,

In literature people often obtain eigenstates of reduced density matrix from a DMRG calculation (e.g. Cincio & Vidal, PRL 110, 067208 (2013)). While there is a nice code formula to calculate the entanglement spectrum, I couldn't find one for this seemingly different task. Is there a way of implemeting this calculation using ITensor? Thanks!

Best,
