• Authors: Monika Leibscher, Jonas Kalveram, Christiane P. Koch
• Abstract summary: Microwave three-wave mixing allows for enantiomer-selective excitation of randomly oriented molecules into rotational states with different energy. We show how to design pulse sequences with maximal enantiomer-selectivity from an analysis of the $M$-dependence of the Rabi frequencies associated with rotational transitions induced by resonant microwave drives.

• Abstract: Microwave three-wave mixing allows for enantiomer-selective excitation of randomly oriented chiral molecules into rotational states with different energy. The random orientation of molecules is reflected in the degeneracy of the rotational spectrum with respect to the orientational quantum number $M$ and reduces, if not accounted for, enantiomer-selectivity. Here, we show how to design pulse sequences with maximal enantiomer-selectivity from an analysis of the $M$-dependence of the Rabi frequencies associated with rotational transitions induced by resonant microwave drives. We compare different excitations schemes for rotational transitions and show that maximal enantiomer-selectivity at a given rotational temperature is achieved for synchronized three-wave mixing with circularly polarized fields.

  We show that the orientation of the angular momentum transferred from the laser field to the rotons, is dictated by the centrifuge. The observed decay of the coherent Raman signal suggests that the decoherence is governed by the scattering on thermal rotons and phonons.

  We experimentally investigate individual spin dynamics in a two-dimensional ensemble of electron spins on the surface of a diamond crystal. We show that this anomalously slow relaxation rate is due to the presence of strong dynamical disorder. Our work paves the way towards microscopic study and control of quantum thermalization in strongly interacting disordered spin ensembles.

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

  In this study polarisation transfer to a heteronucleus is achieved through a selective rotation of the proton singlet-triplet states. Surprisingly we find that efficient polarisation transfer driven by a STORM (Singlet-Triplet Oscillations through Rotating Magnetic fields) pulse in the presence of $mu$T bias fields requires rotation frequencies on the order of several kHz.

A generalization of this interferometric method is presented replacing the two single coherent excitations by arbitrary composite laser pulses. Hyper-clocks based on three-pulse and five-pulse interrogation protocols are studied and shown to exhibit nonlinear cubic and quintic sensitivities to residual probe-induced light-shifts.

  We experimentally excite two different molecular species to two different rotational frequencies of choice. The new level of control is achieved by shaping the centrifuge spectrum according to the rotational spectra of the centrifuged molecules. The technique will expand the utility of rotational control in the studies of the effects of molecular rotation on collisions and chemical reactions.

• Anisotropic electron-nuclear interactions in a rotating quantum spin bath [55.41644538483948]
  Spin-bath interactions are strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance. We show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $13$C nuclear spins introduces decoherence into the system. Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.
