Local control of population transfer in molecules under noise — •Robert Kritzer and Volker Engel — Institut für Physikalische Chemie, Am Hubland, 97074 Würzburg

We investigate the laser induced population transfer between electronic states of Na₂ molecules which are subject to perturbations by noise. In a former paper [1] it was shown, that within the formalism of Local Control Theory laser fields can be constructed which are able to selectively transfer population from the electronic ground to a target excited electronic state. These studies assumed an unperturbed molecular motion. Here, we address the question in how far the efficiency of the control process is reduced by additional perturbations. Therefore, we employ a stochastic Schrödinger equation including a noise-term in the Hamiltonian [2].
