Phys. Rev. A 68, 051402(R) (2003) [4 pages]Optimized time-dependent perturbation theory for pulse-driven quantum dynamics in atomic or molecular systemsSee Also: Publisher's Note
We present a time-dependent perturbative approach adapted to the treatment of intense pulsed interactions. We show there is a freedom in choosing secular terms and use it to optimize the accuracy of the approximation. We apply this formulation to a unitary superconvergent technique and improve the accuracy by several orders of magnitude with respect to the Magnus expansion. © 2003 The American Physical Society URL:
