A path integral ground state replica trick approach for the computation of entanglement entropy of dipolar linear rotors
(AIP Publishing, 2020-05-14)We calculate the second Rényi entanglement entropy for systems of interacting linear rotors in their ground state as a measure of entanglement for continuous rotational degrees of freedom. The entropy is defined in relation ...
