Scaling, multiscaling, and nontrivial exponents in inelastic collision processes.
We investigate velocity statistics of homogeneous inelastic gases using the Boltzmann equation. Employing an approximate uniform collision rate, we obtain analytic results valid in arbitrary dimension. In the freely evolving case, the velocity distribution is characterized by an algebraic large-velocity tail, P(v,t) approximately v(-sigma). The exponent sigma(d,epsilon), a nontrivial root of an...
متن کاملCollision statistics in sheared inelastic hard spheres.
The dynamics of sheared inelastic-hard-sphere systems is studied using nonequilibrium molecular-dynamics simulations and direct simulation Monte Carlo. In the molecular-dynamics simulations Lees-Edwards boundary conditions are used to impose the shear. The dimensions of the simulation box are chosen to ensure that the systems are homogeneous and that the shear is applied uniformly. Various syst...
متن کاملDeep Inelastic Processes
Cut vertices, a generalization of matrix elements of local operators, are revisited, and an expansion in terms of minimally subtracted cut vertices is formulated. An extension of the formalism to deal with semi-inclusive deep inelastic processes in the target fragmentation region is explicitly constructed. The problem of factorization is discussed in detail.
متن کاملEvaluation of Boltzmann Integrals for Inelastic Collision and Radiative Processes in Monatomic
Within the scope of a moment method collision integrals of the Boltzmann type are formulated and evaluated for the different excited particle states of a stationary monatomic plasma macroscopically at rest. All collision and radiative processes except the three body recombination are considered. The calculations are performed within Grad's 8-moment approximation of the momentum distribution fun...
متن کاملHole Fragmentation in Deep - Inelastic Processes ”
For deep inelastic eN and P N processes we argue that there are three fragmentation regions instead of two when w is very large.
