Classical no-cloning theorem under Liouville dynamics by non-Csiszár f-divergence

T. Yamano, O. Iguchi

The Csiszár f-divergence, which is a class of information distances, is known to offer a useful tool for analysing the classical counterpart of the cloning operations that are quan…

Gravitational Fugacity as the seed of self-organized violent relaxaton process toward Local Virial relation

Yasuhide Sota, Osamu Iguchi, Tohru Tashiro +1

We propose the self-organized relaxation process which drives a collisionless self-gravitating system (SGS) to the equilibrium state satisfying local virial (LV) relation. During t…

Local virial relation and velocity anisotropy in self-gravitating system

Y. Sota, O. Iguchi, M. Morikawa +1

We investigate the merging process in N-body self-gravitating system from the viewpoints of the local virial relation which is the relation between the local kinetic energy and the…

Local virial relation for self-gravitating system

Osamu Iguchi, Yasuhide Sota, Akika Nakamichi +1

We demonstrate that the quasi-equilibrium state in self-gravitating -body system after cold collapse are uniquely characterized by the local virial relation using numerical simu…

Local virial relation and velocity anisotropy for collisionless self-gravitating systems

Y. Sota, O. Iguchi, M. Morikawa +1

The collisionless quasi-equilibrium state realized after the cold collapse of self-gravitating systems has two remarkable characters. One of them is the linear temperature-mass (TM…

Universal Non-Gaussian Velocity Distribution in Violent Gravitational Processes

O. Iguchi, Y. Sota, T. Tatekawa +2

We study the velocity distribution in spherical collapses and cluster-pair collisions by use of N-body simulations. Reflecting the violent gravitational processes, the velocity dis…
