Transient spiral arms from far out of equilibrium gravitational evolution
David Benhaiem, Michael Joyce, Francesco Sylos Labini
We describe how a simple class of out of equilibrium, rotating and asymmetrical mass distributions evolve under their self-gravity to produce a quasi-planar spiral structure surrou…
Particle number dependence in the non-linear evolution of N-body self-gravitating systems
David Benhaiem, Michael Joyce, Francesco Sylos Labini +1
Simulations of purely self-gravitating N-body systems are often used in astrophysics and cosmology to study the collisionless limit of such systems. Their results for macroscopic q…
Stationary ordered non-equilibrium states of long-range interacting systems
Michael Joyce, Jules Morand, Pascal Viot
Long-range interacting Hamiltonian systems are believed to relax generically towards non-equilibrium states called "quasi-stationary" because they evolve towards thermodynamic equi…
