We uncover which is the Hamiltonian that has a coherent state as its ground state. Thus, we explain here how coherent states (CS) become eigenfunctions of a displaced quadratic potential V (x) that depends on the CS amplitude α. For each amplitude we have a different V (x). The associated ground state is a coherent state.
