where H is the Hamiltonian of the system (we choose the units so that ~ = 1). If the operator H does not change in time, then, given ψ(0) = ψ0, we have ψ(t) = eψ0. The fundamental solution of the time-dependent Schrodinger equation is the distributional kernel of the solution operator e−itH . For a non-relativistic quantum particle of mass 1 moving in the space of n dimensions in a potential field V (x), the operator H has the form
