Terahertz optoelectronics of quantum rings and nanohelices
T. P. Collier, A. M. Alexeev, C. A. Downing +2
We outline a range of proposals on using quantum rings and nanohelices for terahertz device implementations. We show that an Aharonov-Bohm quantum ring system and a double-gated qu…
All-Dielectric Silicon/Phase-Change Optical Metasurfaces with Independent and Reconfigurable Control of Resonant Modes
Carlota Ruiz de Galarreta, Ivan Sinev, Arseny M. Alexeev +8
All-dielectric metasurfaces consisting of arrays of nanostructured high-refractive-index materials, typically Si, are re-writing what is achievable in terms of the manipulation of…
Two-phonon scattering in graphene in the quantum Hall regime
A. M. Alexeev, R. R. Hartmann, M. E. Portnoi
One of the most distinctive features of graphene is its huge inter-Landau-level splitting in experimentally attainable magnetic fields which results in the room-temperature quantum…
Aharonov-Bohm quantum rings in high-Q microcavities
A. M. Alexeev, I. A. Shelykh, M. E. Portnoi
A single-mode microcavity with an embedded Aharonov-Bohm quantum ring, which is pierced by a magnetic flux and subjected to a lateral electric field, is studied theoretically. It i…
Electric dipole moment oscillations in Aharonov-Bohm quantum rings
A. M. Alexeev, M. E. Portnoi
Magneto-oscillations of the electric dipole moment are predicted and analyzed for a single-electron nanoscale ring pierced by a magnetic flux (an Aharonov-Bohm ring) and subjected…
