Local magnetic resonance of scalar spin chirality
Mar Ferri-Cortés, Joaquin Fernández-Rossier
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 acti…

Remote spin control in Haldane spin chains
Y. del Castillo, A. Ferrón, J. Fernández-Rossier
We consider the remote manipulation of the quantum state of the edge fractional spins of Haldane spin chains using a weak local perturbation on the other edge. We derive an effecti…
