In quantum mechanics, the discrete spectrum of an observable corresponds to the eigenvalues of the operator used to model that observable. According to the mathematical theory of such operators, its eigenvalues are a discrete set of isolated points, which may be either finite or countable . See more A physical quantity is said to have a discrete spectrum if it takes only distinct values, with gaps between one value and the next. The classical example of discrete spectrum (for which … See more Classical mechanics In classical mechanics, discrete spectra are often associated to waves and oscillations in … See more • Band structure • Discrete frequency domain • Decomposition of spectrum (functional analysis) See more WebIn classical mechanics, discrete spectra are often associated to waves and oscillations in a bounded object or domain. Mathematically they can be identified with the eigenvalues of differential operators that describe the evolution of some continuous variable (such as strain or pressure) as a function of time and/or space.
WebNo, the discrete spectrum of eigenvalues is mathematically well understood. What is not understood is why a measurement forces a system to be in one of the eigenstates associated with the measured eigenvalue after the measurement. This is essentially known as the "quantum measurement problem". In physics, particularly in quantum mechanics, some differential operators have discrete spectra, with gaps between values. Common cases include the Hamiltonian and the angular momentum operator.
WebIn summary, if the energy is less than the potential at − ∞ and + ∞, then it is a bound state, and the spectrum will be discrete: Ψ ( x, t) = ∑ n c n Ψ n ( x, t). Otherwise (if the energy is greater than the potential at − ∞ or + ∞ ), it is a scattering state, and the spectrum will be continuous: Ψ ( x, t) = ∫ d k c ( k) Ψ k ( x, t).
