The Boundary Structure of Zero-temperature Driven Hard Spheres
We study the fundamental problem of two gas species whose molecules collide as hard spheres in the presence of a flat boundary and with dependence on only one space dimension. More specifically the steady linear problem considered is the one arising when the second gas dominates as a flow moving towards the boundary with constant microscopic velocity (and hence zero temperature). The boundary c...
متن کاملThe Boundary Convergence of the Steady Zero-temperature-driven Hard Spheres
We study the fundamental problem of two gas species in two dimensional velocity space whose molecules collide as hard circles in the presence of a flat boundary and with dependence on only one space dimension. The case of three-dimensional velocity space is a trivial generalization. More specifically the linear problem arising when the second gas dominates as a flow with constant velocity (and ...
متن کاملThe Most Stable Structure for Hard Spheres
The hard sphere model is known to show a liquid-solid phase transition, with the solid expected to be either face centered cubic or hexagonal close packed. The differences in free energy of the two structures is very small and various attempts have been made to determine which structure is the more stable. We contrast the different approaches and extend one. 1 Research supported in part by NSF ...
متن کاملEvent-driven Brownian dynamics for hard spheres.
Brownian dynamics algorithms integrate Langevin equations numerically and allow to probe long time scales in simulations. A common requirement for such algorithms is that interactions in the system should vary little during an integration time step; therefore, computational efficiency worsens as the interactions become steeper. In the extreme case of hard-body interactions, standard numerical i...
