In physics, specifically in quantum mechanics, a coherent state is the specific quantum state of the quantum harmonic oscillator, often described as a state which has dynamics most closely resembling the oscillatory behavior of a classical harmonic oscillator. It was the first example of quantum dynamics when Erwin Schrödinger derived it in 1926, while searching for solutions of the Schrödinger equation that satisfy the correspondence principle. The quantum harmonic oscillato… WebJan 10, 2024 · Coherent states are not eigenstates of the creation operator $\hat a^\dagger$, which in fact has no eigenstates at all. (It does have 'left' eigenstates, i.e. $ \alpha \hat a^\dagger= \alpha \alpha^*$, but those don't help much.) The inference that 'adding' (or indeed, removing) particles does not change the state is just plain wrong.
