Coherent and Dissipative Spin Torques in Quantum Dots: A Unified Framework for Quantum Spin Dynamics
Dominic Ruckert, Stepan Kovarik, Richard Schlitz +4
The manipulation of single spins through spin-polarized tunneling opens new routes for quantum control at the atomic scale. We present a theoretical framework describing spin-trans…
Intermediate diffusive-ballistic electron conduction around mesoscopic defects in graphene
Toni Markovic, Wei Huang, William S. Huxter +2
Non-diffusive effects in charge transport become relevant as device sizes and features become comparable to the electronic mean free path. As a model system, we investigate the ele…
Spin torque driven electron paramagnetic resonance of a single spin in a pentacene molecule
Stepan Kovarik, Richard Schlitz, Aishwarya Vishwakarma +3
Control over quantum systems is typically achieved by time-dependent electric or magnetic fields. Alternatively, electronic spins can be controlled by spin-polarized currents. Here…
Electron paramagnetic resonance of alkali metal atoms and dimers on ultrathin MgO
Stepan Kovarik, Roberto Robles, Richard Schlitz +4
Electron paramagnetic resonance (EPR) can provide unique insight into the chemical structure and magnetic properties of dopants in oxide and semiconducting materials that are of in…
Accurate measurement of atomic magnetic moments by minimizing the tip magnetic field in STM-based electron paramagnetic resonance
Tom S. Seifert, Stepan Kovarik, Pietro Gambardella +1
Electron paramagnetic resonance (EPR) performed with a scanning tunneling microscope (STM) allows for probing the spin excitation of single atomic species with MHz energy resolutio…
Longitudinal and transverse electron paramagnetic resonance in a scanning tunneling microscope
Tom S. Seifert, Stepan Kovarik, Dominik M. Juraschek +3
Electron paramagnetic resonance (EPR) spectroscopy is widely employed to characterize paramagnetic complexes. Recently, EPR combined with scanning tunneling microscopy (STM) achiev…
