Two-dimensional chiral waveguide quantum electrodynamics: long range qubit correlations and flat-band dark polaritons
Y. Marques, I. A. Shelykh, I. V. Iorsh
We consider a two-dimensional extension of the 1D waveguide quantum electrodynamics and investigate the nature of linear excitations in two-dimensional arrays of qubits coupled to…
Modelling excitonic Mott transitions in two-dimensional semiconductors
A. Kudlis, I. Iorsh
We analyze the many-particle correlations that affect the optical properties of two-dimensional semiconductors. These correlations manifest themselves through the specific optical…
Chiral waveguide optomechanics: first order quantum phase transitions with symmetry breaking/
Denis Sedov, Valerii Kozin, Ivan Iorsh
We present a direct mapping between the quantum optomechanical problem of the atoms harmonically trapped in the vicinity of a chiral waveguide and a generalized quantum Rabi model…
Bosonic Hofstadter butterflies in synthetic antiferromagnetic patterns
Yury S Krivosenko, Ivan V Iorsh, Ivan A Shelykh
The emergence of Hofstadter butterflies for bosons in synthetic-gauge-field antiferromagnetic patterns is theoretically studied. We report on a specific tight-binding model of arti…
Waveguide quantum optomechanics: parity-time phase transitions in ultrastrong coupling regime
Ivan Iorsh, Alexander Poshakinskiy, Alexander Poddubny
We develop a rigorous theoretical framework for interaction-induced phenomena in the waveguide quantum electrodynamics (QED) driven by mechanical oscillations of the qubits. Specif…
High refractive index and extreme biaxial optical anisotropy of rhenium diselenide for applications in all-dielectric nanophotonics
Roman Polozkov, Anton Shubnik, Ivan Shelykh +1
We establish simple quantitative criterium for the search of new dielectric materials with high values of the refractive index in the visible range. It is demonstrated, that for li…
MoG-VQE: Multiobjective genetic variational quantum eigensolver
D. Chivilikhin, A. Samarin, V. Ulyantsev +3
Variational quantum eigensolver (VQE) emerged as a first practical algorithm for near-term quantum computers. Its success largely relies on the chosen variational ansatz, correspon…
Fano resonances in optical spectra of semiconductor quantum wells driven by an oscillating field
O. V. Kibis, S. A. Kolodny, I. V. Iorsh
Optical spectra of semiconductor quantum wells driven by an off-resonant oscillating field are studied theoretically. Due to the dynamical stabilization effect, the field induces t…
Spin-valley dynamics in alloy-based transition metal dichalcogenide heterobilayers
V. Kravtsov, A. D. Liubomirov, R. V. Cherbunin +11
Van der Waals heterobilayers based on 2D transition metal dichalcogenides have been recently shown to support robust and long-lived valley polarization for potential valleytronic a…
Broadband enhancement of second harmonic generation at the domain walls of magnetic topological insulators
Ivan Iorsh, Gulnaz Rakhmanova
We show that the second harmonic generation (SHG) is enhanced in the chiral one-dimensional electron currents in a broad frequency range. The origin of the enhancement is two-fold:…
Tunable optical nonlinearity for TMD polaritons dressed by a Fermi sea
V. Shahnazaryan, V. K. Kozin, I. A. Shelykh +2
We study a system of a transition metal dichalcogenide (TMD) monolayer placed in an optical resonator, where strong light-matter coupling between excitons and photons is achieved.…
Generating -states of surface plasmon-polariton pairs with a nanoparticle
Nikita A. Olekhno, Mihail I. Petrov, Ivan V. Iorsh +2
We consider a generation of two-particle quantum states in the process of spontaneous parametric down-conversion of light by a dielectric nanoparticle with response. As a…
