Acoustoelectric effect in two-dimensional Dirac materials exposed to Rayleigh surface acoustic waves
K. Sonowal, A. V. Kalameitsev, V. M. Kovalev +1
We study the acoustoelectric effect in two-dimensional materials like transition metal dichalcogenide monolayers located on a non-piezoelectric substrate and exposed to the Rayleig…
Optical Transistor for an Amplification of Radiation in a Broadband THz Domain
Kristian Hauser A. Villegas, Fedor V. Kusmartsev, Y. Luo +1
We propose a new type of optical transistor for a broadband amplification of THz radiation. It is made of a graphene--superconductor hybrid, where electrons and Cooper pairs couple…
Bogolon-mediated electron scattering in graphene in hybrid Bose-Fermi systems
Meng Sun, K. H. A. Villegas, V. M. Kovalev +1
We report on an unconventional mechanism of electron scattering in graphene in hybrid Bose- Fermi systems. We study energy-dependent electron relaxation time, accounting for the pr…
Photoinduced electric currents in Bose-Einstein condensates
V. M. Kovalev, I. G. Savenko
We calculate a light-induced electric current which can occur from a Bose-Einstein condensate under the action of an external electromagnetic field with the frequency exceeding the…
Shedding light on topological superconductors
K. H. A. Villegas, V. M. Kovalev, F. V. Kusmartsev +1
We propose an optical approach to monitor superconductors in conjunction with a normal metal layer. Effectively such a hybrid system represents a resonator, where electrons are str…
