RF and MW coils for experimental quantum simulators — •Hüseyin Yildiz, Tobias Hammel, Maximilian Kaiser, Keerthan Subramanian, Matthias Weidemüller, and Selim Jochim — Physikalisches Institut, Universität Heidelberg, Im Neuenheimer Feld 226, 69120 Heidelberg (Germany)

To manipulate the spin degree of ultracold atoms we apply radio frequency (RF) and microwave (MW) magnetic fields. In current experiments it is challenging to realize magnetic field amplitudes that realize sufficiently large Rabi frequencies. It is therefore a major challenge to optimize magnetic field coil designs.

We present optimized and frequency-variable RF and MW coils for the excitation of different states in the Paschen-Back regime of ultracold Lithium-6 atoms and molecules. Fast and controlled changes in resonance frequency of RF and MW coils enable more flexible sequences and shorter sequence times.
