Aspects of quantum information in finite density field theory
Lucas Daguerre, Raimel Medina, Mario Solis +1
We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero c…

Renyi relative entropies and renormalization group flows
Horacio Casini, Raimel Medina, Ignacio Salazar +1
Quantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measu…
