• Abstract: Quantum states with finite scalar spin chirality carry an orbital magnetic moment that has eluded direct measurement. We show that a local drive breaks the cyclic symmetry and activates chirality-changing transitions. We propose two complementary probes: direct chirality resonance and chirality-resolved spin resonance. Lindblad simulations demonstrate their feasibility in locally addressable spin platforms, including scanning tunneling microscopy, silicon donors, and quantum dots.

  In quantum information, the scalar spin chirality is a witness of genuine tripartite entanglement. We propose an indirect measurement scheme, based on the Hadamard test, to estimate the scalar spin chirality for general quantum states. We show a single-shot determination of the scalar chirality is possible for chirality eigenstates, via quantum phase estimation with a single auxiliary qutrit.

The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

• 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.

  We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes. The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments. The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.
