The Fock Space Dynamics of Causal Fermion Systems: Non-Abelian Gauge Fields
Claudio Dappiaggi, Felix Finster, Niky Kamran +1
A limiting case is worked out in which the causal action principle for causal fermion systems describing Minkowski space gives rise to the linear Fock space dynamics of perturbativ…
The essential regularity of singular connections in geometry
Moritz Reintjes, Blake Temple
This paper, a culmination of the authors' theory of the RT-equations, accomplishes the following: (i) We discover there is a true (geometric) regularity associated with every affin…
The Hawking Singularity Theorem for Hölder Continuous Metrics with -Bounded Curvature
Michael Kunzinger, Moritz Reintjes, Roland Steinbauer +1
We prove a low-regularity version of Hawking's singularity theorem for Lorentzian metrics in with Riemann curvature in , where and the dimension of spacet…
Dissipative relativistic fluid flow: A simple Lorentz invariant causal model capturing entropy shocks in its zero viscosity limit
Moritz Reintjes, Adhiraj Chaddha
Zero viscosity limits are central to the study of classical shock waves. By identifying the correct physical (Lax admissible) shocks, they are a cornerstone in the design of analyt…
Static Stellar Phase Transitions in General Relativity and a Generalized Buchdahl Limit
Moritz Reintjes, Ruochen Xia
We give the first general construction of solutions of the static spherically symmetric Einstein-Euler equations, the Tolman-Oppenheimer-Volkoff (TOV-)equation, with prescribed den…
Holographic Mixing and Fock Space Dynamics of Causal Fermion Systems
Claudio Dappiaggi, Felix Finster, Niky Kamran +1
A limiting case is considered in which the causal action principle for causal fermion systems describing Minkowski space gives rise to the linear Fock space dynamics of quantum ele…
