Abstract:
We investigate classical Hamiltonian models for particles interacting with steep differential repulsive barriers both in coordinate and momentum space. The final aim is to define a classical system of many particles behaving as fermions in many respects. In this paper we examine the appearance of the phase portrait of one- or two-particle systems to skim the essential features that would later be transcribed to the basic rules of a molecular dynamics algorithm. One of the remarkable properties of the phase portrait is the flow from states that start far away with a wide range of momentum towards a narrow region in momentum-a virtual locking of momentum-in the vicinity of the steepest part of the barrier in momentum space. The central ideas are developed through two examples in one and two dimensions. © 1995 The American Physical Society.
