Spectrum of the linearized Vlasov--Poisson equation around steady states from galactic dynamics
Matias Moreno, Paola Rioseco, Hanne Van Den Bosch
We study the linearized Vlasov-Poisson equation in the gravitational case around steady states that are decreasing and continuous functions of the energy. We identify the absolutel…
Phase space mixing of a Vlasov gas in the exterior of a Kerr black hole
Paola Rioseco, Olivier Sarbach
We study the dynamics of a collisionless kinetic gas whose particles follow future-directed timelike and spatially bound geodesics in the exterior of a sub-extremal Kerr black hole…
Mixing in an anharmonic potential well
Matías Moreno, Paola Rioseco, Hanne Van Den Bosch
We prove phase-space mixing for solutions to Liouville's equation for integrable systems. Under a natural non-harmonicity condition, we obtain weak convergence of the distribution…
Phase space mixing in an external gravitational central potential
Paola Rioseco, Olivier Sarbach
This article is devoted to the study of the dynamical behavior of a collisionless kinetic gas in d=1,2,3 space dimensions which is trapped in a rotationally symmetric potential wel…
Phase space mixing in the equatorial plane of a Kerr black hole
Paola Rioseco, Olivier Sarbach
It is shown that a collisionless, relativistic kinetic gas configuration propagating in the equatorial plane of a Kerr black hole undergoes a relaxation process and eventually sett…
Spherical steady-state accretion of a relativistic collisionless gas into a Schwarzschild black hole
Paola Rioseco, Olivier Sarbach
In previous work, we derived the most general solution of the collisionless Boltzmann equation describing the accretion of a kinetic gas into a Schwarzschild black hole background,…
Accretion of a relativistic, collisionless kinetic gas into a Schwarzschild black hole
Paola Rioseco, Olivier Sarbach
We provide a systematic study for the accretion of a collisionless, relativistic kinetic gas into a nonrotating black hole. To this end, we first solve the relativistic Liouville e…
Black Hole Solutions for Scale Dependent Couplings: The de Sitter and the Reissner-Nordström Case
Benjamin Koch, Paola Rioseco
Allowing for scale dependence of the gravitational couplings leads to a generalization of the corresponding field equations. In this work, those equations are solved for the Einste…
Scale Setting for Self-consistent Backgrounds
Benjamin Koch, Paola Rioseco, Carlos Contreras
The quest for finding self-consistent background solutions in quantum field theory is closely related to the way one decides to set the renormalization scale . This freedom in t…
Black holes and running couplings: A comparison of two complementary approaches
Benjamin Koch, Carlos Contreras, Paola Rioseco +1
Black holes appear as vacuum solutions of classical general relativity which depend on Newton's constant and possibly the cosmological constant. At the level of a quantum field the…
Exact black hole solution for scale dependent gravitational couplings and the corresponding coupling flow
Carlos Contreras, Benjamin Koch, Paola Rioseco
We study a black hole solution for the generalized Einstein Hilbert action with scale dependent couplings G(r) and Lambda(r). The form of the couplings is not imposed, but rather d…
