Specific term required. Fundamental measure theory is a form of DFT applied to mixtures of these objects. A system of these objects simulated by the Lubachevsky-Stillinger algorithm (15[1])undergoes jamming as these objects are compacted. In the first usage of molecular dynamics, Alder and Wainwright simulated these objects in a box. The excluded volume of these objects is eight times their volume, and their second virial coefficient is equal to four. (-5[1])Formally, these objects are defined as having a pairwise interaction potential of (*) infinity when distance is less than some sigma, (10[1])and zero potential when distance is at least sigma. (-5[1])In kinetic molecular theory, particles have no volume and are assumed to be these objects with a two-word name. (10[1])A common approximation in statistical mechanics is to model particles as, for 10 points, what idealized particles that cannot overlap in space? ■END■ (0[4])
