Natural Energy Bounds in Quantum Thermodynamics
Daniele Guido, Roberto Longo
Given a stationary state for a noncommutative flow, we study a boundedness condition, depending on a positive parameter beta, which is weaker than the KMS equilibrium condition at…

The Bisognano-Wichmann Theorem for Charged States and the Conformal Boundary of a Black Hole
Roberto Longo
Recent applications of Operator Algebras to Quantum Field Theory on a Curved Spacetime show that the incremental entropy associated with a quantum black hole, due the addition of a…

Conformal Nets, Maximal Temperature and Models from Free Probability
C. D'Antoni, R. Longo, F. Radulescu
We consider conformal nets on of von Neumann algebras, acting on the full Fock space, arising in free probability. These models are twisted local, but non-local. We extend to…
