From Landau Equation and Large Deviations to Efficient Simulations of Dynamical Fluctuations
Anwar El Rhirhayi, Jean-Baptiste Fouvry, Julien Barré
The (deterministic) Landau equation captures the mean long-term evolution of dynamically hot long-range interacting finite- systems. Though successful, this kinetic equation fun…
Very long-term relaxation of harmonic 1D self-gravitating systems
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon
One-dimensional self-gravitating systems admit genuine thermodynamical equilibria. For systems with strictly monotonic orbital frequency profile, the Landau and Balescu-Lenard theo…
Thermodynamic blocking in self-gravitating systems
Barnabás Deme, Jean-Baptiste Fouvry
Building upon a thermodynamic formalism, we show that self-gravitating systems in hydrostatic equilibrium with a uniform density are maximal entropy states when submitted to pertur…
Vector Resonant Relaxation and Statistical Closure Theory. II. One-loop Closure
Sofia Flores, Jean-Baptiste Fouvry
We use stellar dynamics as a testbed for statistical closure theory. We focus on the process of "Vector Resonant Relaxation," a long-range, non-linear, and correlated relaxation me…
Kinetic theory of two-dimensional point vortices at order and
Jean-Baptiste Fouvry, Pierre-Henri Chavanis
We investigate the long-term relaxation of a distribution of point vortices in two-dimensional hydrodynamics. To focus on the regime of weak collective amplification, we embed…
On the long-term evolution of razor-thin galactic discs: Balescu-Lenard prediction and perspectives
Mathieu Roule, Jean-Baptiste Fouvry, Christophe Pichon +1
In the last five decades, numerical simulations have provided invaluable insights into the evolution of galactic discs over cosmic times. As a complementary approach, developments…
