Theory of Non-Interacting Fermions and Bosons in the Canonical Ensemble
Hatem Barghathi, Jiangyong Yu, Adrian Del Maestro
We present a self-contained theory for the exact calculation of particle number counting statistics of non-interacting indistinguishable particles in the canonical ensemble. This g…

Operationally accessible entanglement of one dimensional spinless fermions
Hatem Barghathi, Emanuel Casiano-Diaz, Adrian Del Maestro
For indistinguishable itinerant particles subject to a superselection rule fixing their total number, a portion of the entanglement entropy under a spatial bipartition of the groun…

Rényi generalization of the operational entanglement entropy
Hatem Barghathi, C. M. Herdman, Adrian Del Maestro
Operationally accessible entanglement in bipartite systems of indistinguishable particles could be reduced due to restrictions on the allowed local operations as a result of partic…
