WebMar 16, 2016 · A stationary state is an eigenstate of the Hamiltionain $\hat H$ (the energy operator). It is called stationary because when the system is in this state the expectation value $\langle \hat A \rangle$ of any operator $\hat A$ is time independent. A bound state is one that does not go to infinity and is usually $0$ outside a given range of $(x,y,z)$. A stationary state is a quantum state with all observables independent of time. It is an eigenvector of the energy operator (instead of a quantum superposition of different energies). It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or energy eigenket. It is very similar to the concept … See more A stationary state is called stationary because the system remains in the same state as time elapses, in every observable way. For a single-particle Hamiltonian, this means that the particle has a constant probability distribution for … See more An orbital is a stationary state (or approximation thereof) of a one-electron atom or molecule; more specifically, an atomic orbital for an electron in an atom, or a molecular orbital for an electron in a molecule. For a molecule that … See more • Stationary states, Alan Holden, Oxford University Press, 1971, ISBN 0-19-851121-3 See more As shown above, a stationary state is not mathematically constant: However, all observable properties of the state are in fact … See more Spontaneous decay complicates the question of stationary states. For example, according to simple (nonrelativistic) quantum mechanics, the hydrogen atom has many stationary states: 1s, 2s, 2p, and so on, are all stationary states.

WebThe excited state is (a) never sensibly populated and (b) it is not a stationary state so has a finite lifetime. Thus the width of this state (in energy) gives the scattering some very , very small probability of occurring when the photon is non-resonant. $\endgroup$ – porphyrin. WebMar 18, 2024 · Stationary states can also be described by the time-independent Schrödinger equation (used only when the Hamiltonian is not explicitly time dependent). However, it should be noted that the solutions to the time-independent Schrödinger equation still have time dependencies. Time-Dependent Wavefunctions WebSep 12, 2024 · Stationary States.
