WebThe overlap-repulsion and polarization terms of the interaction potential are derived on a purely non empirical, rst-principles basis. For the dispersion, three cases are considered: a rst one in which the dispersion parameters are set … Quantum mechanical particles are classified as bosons or fermions. The spin–statistics theorem of quantum field theory demands that all particles with half-integer spin behave as fermions and all particles with integer spin behave as bosons. Multiple bosons may occupy the same quantum state; however, by the Pauli exclusion principle, no two fermions can occupy the same state. Since electrons have spin 1/2, they are fermions. This means that the overall wave function of a syste…
Webthat they overlap for some range of ρ, before each drops discontinuously into a jammed state. As N increases, the onset value of ρ for jamming increases to a limiting value ρc ≃ 0.84 (consistent with the value for random close packing [3]) and η−1 vanishes continuously. For finite N, systems jam below ρc because there is always a fi- WebJan 22, 2024 · In this "overlap" explanation, the overlap is not an overlap between two electrons.
