Quantum control of molecular rotation — •Dominique Sugny — Université de Bourgogne Europe, Dijon, France

We review recent results on the control of molecular rotation for applications in gas-phase alignment and orientation of linear and symmetric top molecules [1]. We show how control techniques can be applied to produce planar alignment and unidirectional rotational motion. The application of optimal control theory in this context will be discussed. Finally, recent extensions of two- and three-dimensional Anderson localization to rotational dynamics will be proposed. Theoretical and experimental results are presented for the different examples.
