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 $B$ be a spatial region of width $2 R$ and $Φ$ a Klein-Gordon wave packet localized in $B$ at time zero. We show the inequality $S \leq 2 π R E$ ; here, $S$ is the entropy of $Φ$ c…
