Local clustering of relic neutrinos: Comparison of kinetic field theory and the Vlasov equation
Emil Brinch Holm, Stefan Zentarra, Isabel M. Oldengott
Gravitational clustering in our cosmic vicinity is expected to lead to an enhancement of the local density of relic neutrinos. We derive expressions for the neutrino density, using…
Hamiltonian Analysis of Gravity and the Failure of the Dirac-Bergmann Algorithm for Teleparallel Theories of Gravity
Fabio D'Ambrosio, Lavinia Heisenberg, Stefan Zentarra
In recent years, gravity has enjoyed considerable attention in the literature and important results have been obtained. However, the question of how many physical degrees of…
Local clustering of relic neutrinos with kinetic field theory
Emil Brinch Holm, Isabel M. Oldengott, Stefan Zentarra
The density of relic neutrinos is expected to be enhanced due to clustering in our local neighbourhood at Earth. We introduce a novel analytical technique to calculate the neutrino…
Kinetic Field Theory: Higher-Order Perturbation Theory
Lavinia Heisenberg, Shayan Hemmatyar, Stefan Zentarra
We give a detailed exposition of the formalism of Kinetic Field Theory (KFT) with emphasis on the perturbative determination of observables. KFT is a statistical non-equilibrium cl…
Gravitational Waves in Full, Non-Linear General Relativity
Fabio D'Ambrosio, Shaun D. B. Fell, Lavinia Heisenberg +3
These notes provide a student-friendly introduction to the theory of gravitational waves in full, non-linear general relativity (GR). We aim for a balance between physical intuitio…
First-order thermodynamics of Horndeski gravity
Andrea Giusti, Stefan Zentarra, Lavinia Heisenberg +1
We extend to the Horndeski realm the irreversible thermodynamics description of gravity previously studied in "first generation" scalar-tensor theories. We identify a subclass of H…
ADM formulation and Hamiltonian analysis of Coincident General Relativity
Fabio D'Ambrosio, Mudit Garg, Lavinia Heisenberg +1
We consider a simpler geometrical formulation of General Relativity based on non-metricity, known as Coincident General Relativity. We study the ADM formulation of the theory and p…
