Equilibrium states for non relativistic Bose gases and the Gross-Pitaevskii limit
Stefano Galanda, Nicola Pinamonti
In this paper, we present the construction of equilibrium states for a gas of weakly interacting non-relativistic bosons, focusing on the case of a non-trivial background field in…

The Semiclassical Einstein-Klein-Gordon System: Asymptotic Analysis of Minkowski Spacetime
Stefano Galanda, Paolo Meda, Simone Murro +2
We establish the linear instability of the semiclassical Einstein-Klein-Gordon system linearised about the Minkowski vacuum spacetime. The proof relies on formulating a forcing pro…

Haag Duality in the Thermal Sector
Stefano Galanda, Leonardo Sangaletti
We prove that the net of localised von Neumann algebras associated with a real scalar field propagating on Minkowski spacetime, in the KMS representation, satisfies a generalised v…
