Ch 2.3 The operator corresponding to the total energy of the system: $\hat{H} = \hat{T} + \hat{V}$ (kinetic plus potential energy). The Hamiltonian generates time evolution: $i\hbar\partial|\psi\rangle/\partial t = \hat{H}|\psi\rangle$. *See also:* Schrodinger equation, Time evolution operator, Ener
