Propagation Matrices from the Finite Element Method

Optimization of action integrals is suggested as an alternative to initial value algorithms for the study of time-evolving quantum systems. The finite element method provides a convenient and rapidly convergent scheme for some simple cases where analytical solutions are available. Two level systems...

Summary:Optimization of action integrals is suggested as an alternative to initial value algorithms for the study of time-evolving quantum systems. The finite element method provides a convenient and rapidly convergent scheme for some simple cases where analytical solutions are available. Two level systems are given particular attention.
