Far-field terahertz spectroscopy across the charge-density-wave transition in 2H-NbSe
Dmitriy Yavorskiy, Adil Rehman, Wojciech Brzezicki +7
Charge-density-wave (CDW) formation in 2H-NbSe modifies the low-energy electronic structure and gives rise to collective excitations coupled to the lattice. Here, we investigat…
Delayed Formation of Landau Polaritons in Phase-Resolved THz Spectroscopy
Noureddine Charrouj, Yurii Ivonyak, Dmitriy Yavorskiy +4
Strong light-matter coupling gives rise to polaritons through coherent and periodic energy exchange between electromagnetic cavity fields and material excitations. While this inter…
Deep Strong light-matter Coupling in 3D Kane Fermions
Dmitriy Yavorskiy, David Hagenmuller, Noureddine Charrouj +5
Deep strong light-matter coupling represents an extreme non-perturbative regime of quantum electrodynamics, in which the interaction strength exceeds the bare frequencies of the un…
Experiment and kp analysis of the luminescence from modulation-doped CdTe/(Cd,Mg)Te quantum wells at magnetic field
W. Solarska, M. Grymuza, M. Kubisa +8
In spite of a large quantity of papers devoted to the mangetoluminescence from CdTe/(Cd,Mg)Te, quantum wells there have been no attempts to analyze it on the basis of the band-stru…
Effect of temperature on 2D terahertz plasmons and electron effective mass in AlGaN/GaN
M. Dub, P. Sai, D. Yavorskiy +6
The effect of temperature on two-dimensional plasmons in large-area AlGaN/GaN plasmonic crystals was studied experimentally. With the temperature increase the resonant plasmon freq…
Terahertz magnon-polaritons control using a tunable liquid crystal cavity
Dmitriy Yavorskiy, Jan Suffczyński, Rafał Kowerdziej +4
Strong coupling of light to a collective spin excitation in antiferromagnets gives rise to hybrid modes called magnon-polaritons. They are highly promising for data manipulation an…
Low-energy excitations in multiple modulation-doped CdTe/(CdMg)Te quantum wells
D. Yavorskiy, F. Le Mardelé, I. Mohelsky +6
Low energy excitations of a two-dimensional electron gas (2DEG) in modulation-doped multiple (ten) quantum wells (QWs) was studied using far-infrared magneto-transmission technique…
Extreme Terahertz Nonlinearity of AlGaN/GaN-based Grating-Gate Plasmonic Crystals
Pavlo Sai, Vadym V. Korotyeyev, Dmytro B. But +12
We present a novel approach to enhance THz nonlinearity by the resonant excitation of two-dimensional plasmons in grating-gate plasmonic crystals. Using a high-electric-field THz p…
Optical bound states in the continuum in subwavelength gratings made of an epitaxial van der Waals material
Emilia Pruszyńska-Karbownik, Tomasz Fąs, Katarzyna Brańko +9
High refractive index (4.4 at 1100 nm), negligibly small absorption in near-infrared spectral range, and ease of processing make MoSe a perfect material for applications in nea…
Pressure tuning of HgCdTe epitaxial layers -- the role of the highly disordered buffer layer
D. Yavorskiy, Y. Ivonyak, D. But +9
HgCdTe alloys are unique because by increasing the Cd content x, one modifies the band structure from inverted to normal, which fundamentally modifies the dispersion of bulk and su…
Beatings of ratchet current magneto-oscillations in GaN-based grating gate structures: manifestation of spin-orbit band splitting
P. Sai, S. O. Potashin, M. Szola +8
We report on the study of the magnetic ratchet effect in AlGaN/GaN heterostructures superimposed with lateral superlattice formed by dual-grating gate structure. We demonstrate tha…
