In a stationary state
WebAug 28, 2024 · Stationary state is usually used in quantum mechanics. When a wavefunction is in a stationary state, it does not change in time, and ( I presume) it has never earlier been in any other state, and will never be in another state, unless the system changes. For example, a wavefunction can be in a stationary state in a finite well with length a ... 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 $(x,y,z)$.
