Minimum-entropy constraints on galactic potentials
Leandro Beraldo e Silva, Monica Valluri, Eugene Vasiliev +3
A tracer sample in a gravitational potential, starting from a generic initial condition, phase-mixes towards a stationary state. This evolution is accompanied by an entropy increas…
The discreteness-driven relaxation of collisionless gravitating systems: entropy evolution in external potentials, N-dependence and the role of chaos
Leandro Beraldo e Silva, Walter de Siqueira Pedra, Monica Valluri +2
We investigate the old problem of the fast relaxation of collisionless -body systems which are collapsing or perturbed, emphasizing the importance of (non-collisional) discreten…
The Arrow of Time in the collapse of collisionless self-gravitating systems: non-validity of the Vlasov-Poisson equation during violent relaxation
Leandro Beraldo e Silva, Walter de Siqueira Pedra, Laerte Sodré +2
The collapse of a collisionless self-gravitating system, with the fast achievement of a quasi-stationary state, is driven by violent relaxation, with a typical particle interacting…
