تعريف density of states في الإنجليزية الإنجليزية القاموس.

In statistical and condensed matter physics, Density of states (DOS) is a property that quantifies how closely packed energy levels are in a quantum-mechanical system. It is usually denoted with one of the symbols g, , n, or N. It is a function g(E) of the internal energy E, such that the expression g(E) dE represents the number of states with energies between E and E+dE. It can also be written as a function of the angular frequency , which is proportional to the energy. The density of states is used extensively in condensed-matter physics, where it can refer to electron, photon, or phonon energy levels in a crystalline solid. In crystalline solids, there are often energy ranges where the density of electron states is zero, which means that the electrons cannot be excited to these energies. The density of states also occurs in Fermi's golden rule, which describes how fast quantum-mechanical transitions occur in the presence of a perturbation
