Spin separation of Dirac electrons by twisted and vector optical beams
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
We demonstrate that twisted and vector optical beams can spatially separate two-dimensional electrons with opposite spin projections. Spin accumulation arises from diverging spin c…
Twist tunable resonances in photonic bilayer for second harmonic generation
Egor S. Vyatkin, Sergey A. Tarasenko
Moiré structure emerging in photonic bilayers stacked with a twist enables the controllable frequency selective resonant response. Here, we employ twist tunable resonances to boost…
Electric and spin-valley currents induced by structured light in 2D Dirac materials
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
Structured optical fields can be used for the injection and control of charge and spin-valley currents. Here, we present a systematical study of these phenomena for interband absor…
Resonant enhancement of second harmonic generation in 2D nonlinear crystal integrated with meta-waveguide: analytical vs numerical approaches
Egor S. Vyatkin, Sergey A. Tarasenko
We present an analytical theory of second harmonic generation (SHG) in hybrid structures combining a nonlinear 2D crystal with a dielectric metasurface waveguide. The theory descri…
Trembling motion of electrons driven by Larmor spin precession
I. Stepanov, M. Ersfeld, A. V. Poshakinskiy +4
We show that the initialization of an ensemble of electrons in the same spin state in strained n-InGaAs subject to a perpendicular magnetic field triggers an AC electric current at…
Second harmonic generation due to spatial structure of radiation beam
A. A. Gunyaga, M. V. Durnev, S. A. Tarasenko
We show that spatially structured radiation generates second harmonic in a two-dimensional system even if the system is homogeneous and isotropic. The effect originates from non-lo…
Emergent spin and orbital angular momentum of light in twisted photonic bilayer
Egor S. Vyatkin, Alexander V. Poshakinskiy, Sergey A. Tarasenko
We demonstrate that the optical response of twisted photonic bilayers, photonic counterparts of van der Waals structures, is sensitive to both spin angular momentum (SAM) and orbit…
Terahertz Magnetospectroscopy of Cyclotron Resonances from Topological Surface States in Thick Films of CdHgTe
M. Otteneder, D. Sacré, I. Yahniuk +10
We present studies of the cyclotron resonance (CR) in thick CdHgTe films with different cadmium concentrations corresponding to inverted and normal band order, as well…
Valley polarization induced second harmonic generation in graphene
L. E. Golub, S. A. Tarasenko
The valley degeneracy of electron states in graphene stimulates intensive research of valley-related optical and transport phenomena. While many proposals on how to manipulate vall…
Reflection of short polarized optical pulses from periodic and aperiodic multiple quantum well structures
A. V. Poshakinskiy, A. N. Poddubny, S. A. Tarasenko
We study the reflection of polarized optical pulses from resonant photonic structures formed by periodic, Fibonacci, and gradient sequences of quantum wells. The form and polarizat…
Valley separation in graphene by polarized light
L. E. Golub, S. A. Tarasenko, M. V. Entin +1
We show that the optical excitation of graphene with polarized light leads to the pure valley current where carriers in the valleys counterflow. The current in each valley originat…
