The Schroedinger evolution operator expanded exponentially

Creators

Description

A formal solution of the Schroedinger evolution equation in exponential form is given. Arbitrary nn Pade approximation to the evolution operator is shown to be unitary and bounded, and to lead to a stable implicit numerical method for solving time-dependent Schroedinger equation
