A Quantum Dominant Energy Condition
Stefan Hollands, Roberto Longo, Gerardo Morsella
We propose a quantum dominant energy condition (QDEC) for the stress tensor in the context of quantum field theory in curved spacetimes. A rigorous proof is given for the case of R…
Bekenstein's bound for wave packets
Stefan Hollands, Roberto Longo, Gerardo Morsella
Let be a spatial region of width and a Klein-Gordon wave packet localized in at time zero. We show the inequality ; here, is the entropy of c…
The modular Hamiltonian in asymptotically flat spacetime conformal to Minkowski
Claudio Dappiaggi, Vincenzo Morinelli, Gerardo Morsella +1
We consider a four-dimensional globally hyperbolic spacetime conformal to Minkowski spacetime, together with a massless, conformally coupled scalar field. Using a bulk-to-b…
The fermionic massless modular Hamiltonian
Francesca La Piana, Gerardo Morsella
We provide an explicit expression for the modular hamiltonian of the von Neumann algebras associated to the unit double cone for the (fermionic) quantum field theories of the 2-com…
Quasi-free isomorphisms of second quantisation algebras and modular theory
Roberto Conti, Gerardo Morsella
Using Araki-Yamagami's characterization of quasi-equivalence for quasi-free representations of the CCRs, we provide an abstract criterion for the existence of isomorphisms of secon…
The massless modular Hamiltonian
Roberto Longo, Gerardo Morsella
We compute the vacuum local modular Hamiltonian associated with a space ball region in the free scalar massless Quantum Field Theory. We give an explicit expression on the one part…
