In a stationary state
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
