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…
Electric-field-driven spin resonance by on-surface exchange coupling to a single-atom magnet
Soo-hyon Phark, Hong T. Bui, Alejandro Ferrón +7
Coherent control of individual atomic and molecular spins on surfaces has recently been demonstrated by using electron spin resonance (ESR) in a scanning tunneling microscope (STM)…
Tuning the exchange bias on a single atom from 1 mT to 10 T
Kai Yang, William Paul, Fabian D. Natterer +8
Shrinking spintronic devices to the nanoscale ultimately requires localized control of individual atomic magnetic moments. At these length scales, the exchange interaction plays im…
Engineering the eigenstates of coupled spin-1/2 atoms on a surface
Kai Yang, Yujeong Bae, William Paul +8
Quantum spin networks having engineered geometries and interactions are eagerly pursued for quantum simulation and access to emergent quantum phenomena such as spin liquids. Spin-1…
Exchange mechanism for electron paramagnetic resonance of individual adatoms
J. L. Lado, A. Ferron, J. Fernandez-Rossier
We propose a new universal mechanism that makes it possible to drive an individual atomic spin using a spin polarized scanning tunnel microscope (STM) with an oscillating electric…
Mesoscopic fluctuations in biharmonically driven flux qubits
Alejandro Ferrón, Daniel Domínguez, María José Sánchez
We investigate flux qubits driven by a biharmonic magnetic signal, with a phase lag that acts as an effective time reversal broken parameter. The driving induced transition rate be…
