Statistical Mechanics of Self–Gravitating System : Cluster Expansion Method
We study statistical mechanics of the self–gravitating system applying the cluster expansion method developed in solid state physics. By summing infinite series of diagrams, we derive a complex free energy whose imaginary part is related to the relaxation time of the system. Summation of another series yields two–point correlation function whose correlation length is essentially given by the Je...
متن کاملThe Cluster Expansion in Statistical Mechanics*
The Glimm-Jaffe-Spencer cluster expansion from constructive quantum field theory is adapted to treat quantum statistical mechanical systems of particles interacting by finite range potentials. The Hamiltonian H 0 + Vneed be stable in the extended sense that Ho +4V+BN>O for some B. In this situation, with a mild technical condition on the potentials, the cluster expansion converges and the infin...
متن کاملStatistical mechanics and phase diagrams of rotating self-gravitating fermions
We compute statistical equilibrium states of rotating self-gravitating systems enclosed within a box by maximizing the Fermi-Dirac entropy at fixed mass, energy and angular momentum. The Fermi-Dirac distribution describes quantum particles (fermions) subject to Pauli’s exclusion principle. It is also a typical prediction of Lynden-Bell’s theory of violent relaxation for collisionless stellar sy...
متن کاملStatistical mechanics of relativistic one-dimensional self-gravitating systems.
We consider the statistical mechanics of a general relativistic one-dimensional self-gravitating system. The system consists of N particles coupled to lineal gravity and can be considered as a model of N relativistically interacting sheets of uniform mass. The partition function and one-particle distribution functions are computed to leading order in 1/c where c is the speed of light; as c --> ...
متن کاملThe statistical mechanics of self-gravitating Keplerian disks
We describe the dynamics and thermodynamics of collisionless particle disks orbiting a massive central body, in the case where the disk mass is small compared to the central mass, the self-gravity of the disk dominates the non-Keplerian force, and the spread in semi-major axes is small. We show that with plausible approximations such disks have logarithmic two-body interactions and a compact ph...
