Optimal Control of Spin Ensembles with Inhomogeneous Control Field — •Björn Bartels and Florian Mintert — Freiburg Institute for Advanced Studies, Albert-Ludwigs-Universität Freiburg, Albertstr. 19, 79104 Freiburg, Germany

Our aim is to control spin ensembles in the presence of inhomogeneities of an externally applied control field. Optimal control theory provides us with tools to do this with high accuracy, but typical control pulses contain a broad frequency spectrum with components that might lie outside the experimentally accessible range. To avoid this, we employ pulse shaping techniques in frequency space, what allows us to limit a control pulse to predefined frequency components.
