A disturbance in the force. How force fluctuations hinder dynamical friction and induce core stalling
Pierfrancesco Di Cintio, Bruno Marcos
Dynamical friction is an important phenomena in stellar dynamics resulting in the slowing down of a test particle upon many two-body scatters with background particles. Chandrasekh…
Integrating factor techniques applied to the Schrödinger-like equations. Comparison with Split-Step methods
Martino Lovisetto, Didier Clamond, Bruno Marcos
The nonlinear Schrödinger and the Schrödinger-Newton equations model many phenomena in various fields. Here, we perform an extensive numerical comparison between splitting methods…
Experimental observation of violent relaxation and the formation of out-of-equilibrium quasi-stationary states
M. Lovisetto, M. C. Braidotti, R. Prizia +6
Large scale structures in the Universe, ranging from globular clusters to entire galaxies, are the manifestation of relaxation to out-of-equilibrium states that are not described b…
Optimized integrating factor technique for Schrödinger-like equations
Martino Lovisetto, D Clamond, B Marcos
The integrating factor technique is widely used to solve numerically (in particular) the Schrödinger equation in the context of spectral methods. Here, we present an improvement of…
Towards a measurement of the Debye length in very large Magneto-Optical traps
Julien Barré, Robin Kaiser, Guillaume Labeyrie +2
We propose different experimental methods to measure the analog of the Debye length in a very large Magneto-Optical Trap, which should characterize the spatial correlations in the…
Two-temperature Brownian dynamics of a particle in a confining potential
Vincent Mancois, Bruno Marcos, Pascal Viot +1
We consider the two dimensional motion of a particle into a confining potential, subjected to Brownian forces, associated with two different temperatures on the orthogonal directio…
