A Positive Mass Theorem for Static Causal Fermion Systems
Felix Finster, Andreas Platzer
Asymptotically flat static causal fermion systems are introduced. Their total mass is defined as a limit of surface layer integrals which compare the measures describing the asympt…
Stationary Spacetimes and Self-Adjointness in Klein-Gordon Theory
Felix Finster, Albert Much, Robert Oeckl
We consider the problem of essential self-adjointness of the spatial part of the Klein-Gordon operator in stationary spacetimes. This operator is shown to be a Laplace-Beltrami typ…
Summing over spacetime dimensions in quantum gravity
Erik Curiel, Felix Finster, J. M. Isidro
Quantum-gravity corrections (in the form of a minimal length) to the Feynman propagator for a free scalar particle in are shown to be the result of summing over all…
Two-Dimensional Area and Matter Flux in the Theory of Causal Fermion Systems
Erik Curiel, Felix Finster, J. M. Isidro
The notions of two-dimensional area, Killing fields and matter flux are introduced in the setting of causal fermion systems. It is shown that for critical points of the causal acti…
Causal Fermion Systems: An Elementary Introduction to Physical Ideas and Mathematical Concepts
Felix Finster, Maximilian Jokel
We give an elementary introduction to the theory of causal fermion systems, with a focus on the underlying physical ideas and the conceptual and mathematical foundations.
A Gauge Fixing Procedure for Causal Fermion Systems
Felix Finster, Sebastian Kindermann
Causal fermion systems incorporate local gauge symmetry in the sense that the Lagrangian and all inherent structures are invariant under local phase transformations of the physical…
