The homogeneous cooling process of binary mixtures large aspherical particles and small spheres is modeled using DEM. dissipation rate increases with the increasing total solid volume fraction mixture. For a specified mixture, ratio in Energy equipartition analysis shows that translational rotational components granular temperature for are generally equivalent. also present between particles. B...

The authors study the fundamental properties of scattering amplitudes particles in any spacetime dimension. They introduce binary geometries, giving a completely rigid geometric realization combinatorics generalized associahedra attached to Dynkin diagram. Furthermore, they define open and closed ``cluster string integrals'', which provide generalization particle amplitudes, enjoy remarkable fa...

The phase diagram of binary mixtures of particles interacting via a pair potential of parallel dipoles is computed at zero temperature as a function of composition and the ratio of their magnetic susceptibilities. Using lattice sums, a rich variety of different stable crystalline structures is identified including AmBn structures. [A (B) particles correspond to large (small) dipolar moments.] T...

A simple question of celestial mechanics is investigated: in what regions of phase space near a binary system can planets persist for long times? The planets are taken to be test particles moving in the field of an eccentric binary system. A range of values of the binary eccentricity and mass ratio is studied, and both the case of planets orbiting close to one of the stars, and that of planets ...

This article provides a concise review of selected topics in the many-body physics of low density nuclear systems. The discussion includes the condensation of alpha particles in supernova envelopes, formation of three-body bound states and the BEC-BCS crossover in dilute nuclear matter, and neutrino production in S-wave paired superfluid neutron matter.
