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