On the Conicality of Causally Simple, Future Cohesive Spacetimes
Claudio F. Paganini
The notion of conicality, recently introduced in [2403.00916], captures the extent to which the joint future of a finite set in spacetime uniquely determines the generating subset…
Quantum Reference Frames and Correlation Geometry
Claudio F. Paganini
The aim of this paper is to provide a largely self-contained, compact and comprehensible introduction to the basic ideas behind correlation geometry, which underlies the theory of…
Causal Fermion Systems, Non-Commutative Geometry and Generalized Trace Dynamics
Shane Farnsworth, Felix Finster, Claudio F. Paganini +1
We compare the structures and methods in the theory of causal fermion systems with generalized trace dynamics and non-commutative geometry. Although the three theories differ on ma…
A Collapse Mechanism Without Heating
Felix Finster, Claudio F. Paganini
It is shown that the collapse model derived from the theory of causal fermion systems does not give rise to a heating of the probe. Experimental consequences are worked out. The co…
Pseudodifferential Weyl calculus on vector bundles
Lars Andersson, Benjamin Moser, Marius A. Oancea +2
We develop a geometric framework for Weyl quantization on pseudo-Riemannian manifolds, in which pseudodifferential operators act on sections of vector bundles equipped with pseudo-…
Causal Fermion Systems: Spacetime as the web of correlations of a many-body quantum system
Patrick Fischer, Claudio F. Paganini
In this paper, we argue that spacetime in causal fermion systems can be understood as the web of correlations of a many-body quantum system.This argument highlights the fact that c…
