Exact Mutual Information Difference: Scalar vs. Maxwell Fields
Nicolás Abate, Horacio Casini, Marina Huerta +1
We compute, for any Rényi index , the exact difference between the mutual Rényi informations of a pair of free massless scalars and that of a Maxwell field in dimensions…

Entanglement negativity for a free scalar chiral current
Malen Arias, Marina Huerta, Andrei Rotaru +1
We study the entanglement negativity for the free, scalar chiral current in two spacetime dimensions, which is a simple model violating the Haag duality in regions with nontrivial…
