Giant resonant nonlinear THz valley Hall effect in 2D Dirac semiconductors
V. N. Ivanova, V. M. Kovalev, I. G. Savenko
We predict a giant cyclotron resonance in the nonlinear valley Hall response of inversion-asymmetric two-dimensional semiconductors subjected to crossed terahertz electric and stat…
Conductivity of charge-neutral multicomponent 2D electron-hole system
Yuping Huang, O. V. Kibis, V. M. Kovalev +1
The interplay between distinct carrier species in systems with broken Galilean invariance can give rise to a rich landscape of interaction-driven transport phenomena. Here, we deve…
Interactions-controlled magnetotransport in two-dimensional massless-massive fermion mixtures
Y. Huang, D. S. Eliseev, V. M. Kovalev +3
The presence of two types of holes, namely the Dirac holes and the massive holes, in a two-dimensional sample exposed to an external permanent magnetic field leads to the emergence…
Electronic states bound by repulsive potentials in graphene irradiated by a circularly polarized electromagnetic field
O. V. Kibis, M. V. Boev, I. V. Iorsh +1
In the framework of the Floquet theory of periodically driven quantum systems, it is demonstrated that irradiation of graphene by a circularly polarized electromagnetic field induc…
Renormalization of the valley Hall conductivity due to interparticle interaction
D. S. Eliseev, A. V. Parafilo, V. M. Kovalev +2
We develop a theory of Coulomb interaction-mediated contribution to valley Hall effect (VHE) in two-dimensional non-centrosymmetric gapped Dirac materials. We assume that the bare…

V. M. Kovalev, A. V. Parafilo, O. V. Kibis +1
We develop a theory of Coulomb interaction-related contribution to the photogalvanic current of the carriers of charge in two-dimensional non-centrosymmetric Dirac materials posses…

A. V. Parafilo, V. M. Kovalev, I. G. Savenko
We study the influence of many-body interactions on the transport properties in a two-site charge Kondo circuit recently implemented in a hybrid metal-semiconductor double-quantum…
All-optical control of excitons in semiconductor quantum wells
V. M. Kovalev, M. V. Boev, O. V. Kibis
Applying the Floquet theory, we developed the method to control excitonic properties of semiconductor quantum wells by a high-frequency electromagnetic field. It is demonstrated, p…
Unconventional Bloch-Grüneisen scattering in hybrid Bose-Fermi systems
Kristian Hauser A. Villegas, Meng Sun, Vadim M. Kovalev +1
We report on the novel mechanism of electron scattering in hybrid Bose-Fermi systems consisting of a two-dimensional electron gas in the vicinity of an exciton condensate: We show…
Magnetoplasmon Fano resonance in Bose-Fermi mixtures
M. V. Boev, V. M. Kovalev, I. G. Savenko
We investigate theoretically the magnetoplasmon (cyclotron) resonance in a hybrid system consisting of spatially separated two-dimensional layers of electron and dipolar exciton ga…
