WebThe meaning of STATIONARY STATE is a stable or metastable quantum state. WebSince the stationary state is an eigenstate of H^, the uncertainty H^ of the Hamiltonian in a stationary state is zero. There are two important observations on stationary states: 2. h i (1) The expectation value of any time-independent operator Q^ on a stationary state is time-independent: hQi = ^ Z dx (x;t)Q (x;t) = Z dxeiEt=~
WebNov 8, 2024 · Transitional States. Let's start by refreshing our memory that a general quantum state can be written – using the completeness relation – as a linear combination of stationary states ( Equation 2.4.14 ): Ψ(t) = ∑ n Cn En e − iEn ℏt. Technically, we need to include all the quantum numbers in the linear combination.
