Automated identification of quasi-BIC modes in disordered resonator chains using spatial field envelopes and resonance descriptors
Vadim A. Porvatov, Kliment V. Semushev, Ravshanjon Kh. Nazarov +4
Structural disorder turns bound states in the continuum (BICs) into quasi-BIC resonances and mixes them with spectrally close eigenmodes, so the target mode must be identified anew…
Phase-Flow Topology of Bound States in the Continuum
Nikolai A. Vlasov, Varvara P. Panurchenko, Ravshanjon Kh. Nazarov +3
Control of topological charges of bound states in the continuum (BICs) is essential for advanced topological photonics. A rigorous theoretical framework for understanding the forma…
The algebra and two-dimension electron Green's function in the field of magnetic monopole
P. S. Sidorov, N. A. Vlasov, I. S. Terekhov +1
Using the operator method and properties of algebra, the integral representation for the two-dimensional Green's function of an electron in the field of a magnetic monopol…
Robustness of bound states in the continuum in metasurface based on GeSbTe versus structural imperfections
Nikolai A. Vlasov, Alexander I. Solomonov, Zarina F. Kondratenko +3
We study the impact of lithography imperfections on quasi-bound states in the continuum (quasi-BICs) supported by a one-dimensional metasurface of GeSbTe (GST) bars wit…
Electron scattering by a magnetic monopole in solid-state experiments
P. S. Sidorov, N. A. Vlasov, I. S. Terekhov +1
The scheme of experiment for studying electron scattering in the field of a magnetic monopole in two dimensional electron gas is proposed. The differential scattering cross section…
Angular momentum flux of twisted light in paraxial and nonparaxial regimes
N. A. Vlasov, N. V. Filina, S. S. Baturin
We present a theoretical framework for the derivation of the -directed total angular momentum density of a Bessel wave and of the corresponding intercepted angular momentum flux…
