Feynman path integrals on compact Lie groups with bi-invariant Riemannian metrics
Nicoló Drago, Sonia Mazzucchi, Valter Moretti
In this work we consider a suitable generalization of the Feynman path integral on a specific class of Riemannian manifolds consisting of compact Lie groups with bi-invariant Riema…
On the Relativistic Spatial Localization for massive real scalar Klein-Gordon quantum particles
Valter Moretti
I rigorously analyze a proposal, introduced by D.R.Terno, about a spatial localization observable for a Klein-Gordon massive real particle in terms of a Poincaré-covariant family o…
The quantization of Proca fields on globally hyperbolic spacetimes: Hadamard states and Møller operators
Valter Moretti, Simone Murro, Daniele Volpe
This paper deals with several issues concerning the algebraic quantization of the real Proca field in a globally hyperbolic spacetime and the definition and existence of Hadamard s…
Paracausal deformations of Lorentzian metrics and Møller isomorphisms in algebraic quantum field theory
Valter Moretti, Simone Murro, Daniele Volpe
Given a pair of normally hyperbolic operators over (possibily different) globally hyperbolic spacetimes on a given smooth manifold, the existence of a geometric isomorphism, called…
On the global Hadamard parametrix in QFT and the signed squared geodesic distance defined in domains larger than convex normal neighbourhoods
Valter Moretti
We consider the global Hadamard condition and the notion of Hadamard parametrix whose use is pervasive in algebraic QFT in curved spacetime (see refences in the main text). We poin…
The classical limit of Schrödinger operators in the framework of Berezin quantization and spontaneous symmetry breaking as emergent phenomenon
Valter Moretti, Christiaan J. F. van de Ven
The algebraic properties of a strict deformation quantization are analysed on the classical phase space $\bR^{2n}$. The corresponding quantization maps enable us to take the limit…
