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…
Equilibrium states for non relativistic Bose gases with condensation
Stefano Galanda, Nicola Pinamonti
In this paper we present the construction of the equilibrium states at positive temperature in the presence of a condensation phase for a Gas of non relativistic Bose particles on…
Perturbative Construction of Equilibrium States for Interacting Fermionic Field Theories
Stefano Galanda
In this paper, we aim to extend to interacting massive and massless fermionic theories the recent perturbative construction of equilibrium states developed within the framework of…
Secular growths and their relation to equilibrium states in perturbative QFT
Stefano Galanda, Nicola Pinamonti, Leonardo Sangaletti
In the perturbative treatment of interacting quantum field theories, if the interaction Lagrangian changes adiabatically in a finite interval of time, secular growths may appear in…
Entropy-area law and temperature of de Sitter horizons from modular theory
Edoardo D'Angelo, Markus B. Fröb, Stefano Galanda +3
We derive an entropy-area law for the future horizon of an observer in diamonds inside the static patch of de Sitter spacetime, taking into account the backreaction of quantum matt…
Relative Entropy of Fermion Excitation States on the CAR Algebra
Stefano Galanda, Albert Much, Rainer Verch
The relative entropy of certain states on the algebra of canonical anticommutation relations (CAR) is studied in the present work. The CAR algebra is used to describe fermionic deg…
Relative Entropy for Fermionic Quantum Field Theory
Stefano Galanda
We study the relative entropy, in the sense of Araki, for the representation of a self-dual CAR algebra . We notice, for a specific choice of $f…
