Improved power series expansion for the time evolution operator: Application to two-dimensional systems
The power series expansion formalism is used to construct analytical approximations for the propagator of the partial differential equation of a generic type. The present approach is limited to system...

Managing singular behavior in the tracking control of quantum dynamical observables
Singularities can arise in the external field obtained by tracking control of quantum mechanical systems. Whether or not the trajectory is disturbed by the presence of a singular point is shown to mai...

We present an implementation of an additional cost in the functional of the recently published iteration methods for quantum optimal control [W. Zhu, J. Botina, and H. Rabitz, J. Chem. Phys. 108, 1953 (1998)] to design optimal laser pulses for population transfer. The additional criterion takes into account the asymptotic switch on and off behavior of experimentally generated laser pulses. Exemplarily, a specially adapted windowed Fourier transform is applied to decompose a complex, highly nonintuitive optimal laser field in a sequence of subpulses to provide laser pulse parameters as helpful information for experimental reconstruction. Numerical calculations for three typical spectroscopic excitation mechanisms show that laser fields obtained with the new functional signify a step towards experimental feasibility. ©1999 American Institute of Physics.
