Entanglement Entropy of Periodic Sublattices
Temple He, Javier M. Magan, Stefan Vandoren
We study the entanglement entropy (EE) of Gaussian systems on a lattice with periodic boundary conditions, both in the vacuum and at nonzero temperatures. By restricting the reduce…

Codification Volume of an operator algebra and its irreversible growth through thermal processes
Javier M. Magan, Simone Paganelli
Given a many-body system, we define a quantity, the Codification Volume of an operator algebra, which measures the size of the subspace with whom a given algebra is correlated. We…
