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…

Frequency upconversion of infrared signals via molecular optomechanical cavities
Fen Zou, Shu-Xian Quan, Yong Li +1
Molecular optomechanical cavities have recently emerged as a promising platform for frequency upconversion, enabling the quantum coherent conversion of infrared signal into the vis…
