Experimental observation of exceptional bound states in the continuum
Shuang Wu, Ruizhi Dong, Nikolay Solodovchenko +3
We experimentally demonstrate second- and third-order exceptional bound states in the continuum (EP-BICs), formed by the merging of two and three symmetry-protected BICs at an exce…
Resonant state expansion for acoustic resonators. Part I. Eigenvalue problem
Egor Domoratskii, Vladimir Igoshin, Nikolay Solodovchenko +4
Resonant-state expansion (RSE) is a powerful modal framework for the perturbative analysis of open resonant systems, providing direct access to complex eigenfrequencies and eigenmo…
Resonant state expansion for acoustic resonators. Part II. Scattering problem
Egor Domoratskii, Vladimir Igoshin, Nikolay Solodovchenko +4
We develop a resonant-state expansion formulation for acoustic scattering by individual resonators. The scattered pressure and particle-velocity fields are expanded over the resona…
Optical Theorem for Measuring the Acoustic Extinction Cross Section of Helmholtz Resonators
Vladimir Igoshin, Daniil Klimov, Yuri Utkin +5
The optical theorem is a powerful tool of scattering theory that directly relates the extinction cross section of a scatterer to its forward scattering amplitude. While widely used…
Experimental Investigation of Acoustic Kerker Effect in Labyrinthine Resonators
Iuliia Timankova, Mikhail Smagin, Mikhail Kuzmin +4
Controlling the directionality of the acoustic scattering with single acoustic metaatoms has a key importance for reaching spatial routing of sound with acoustic metamaterials. In…
Optical Spintronics: Towards Optical Communication Without Energy Transfer
Ilya Deriy, Danil Kornovan, Mihail Petrov +1
Energy, momentum, and angular momentum are fundamental properties tied to the symmetries of space and time, with photons and other elementary particles acting as carriers of these…
Excitation of surface plasmon-polaritons through optically-induced ultrafast transient gratings
Olesia Pashina, Albert Seredin, Giulia Crotti +4
Ultrafast excitation of non-equilibrium carriers under intense pulses offer unique opportunities for controlling optical properties of semiconductor materials. In this work, we pro…
