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…

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…
