WebHere, the authors show that the entanglement spectrum -- a fingerprint of the quantum many-body wave function -- of strongly correlated fermionic systems can be evaluated almost exactly by density embedding theory. An accurate entanglement spectrum guarantees the accuracy of the local density matrix or the physical properties, and their …
