Circuit analog of quadratic optomechanics
Eun-jong Kim, J. R. Johansson, Franco Nori
We propose a superconducting electrical circuit that simulates a quadratic optomechanical system. A capacitor placed between two transmission-line (TL) resonators acts like a semi-…

We investigate the nonlinear interaction between a squeezed cavity mode and a mechanical mode in an optomechanical system (OMS) that allows us to selectively obtain either a radiat…
Optomechanically-Induced Transparency in partiy-time-symmetric microresonators
H. Jing, S. K. Özdemir, Z. Geng +5
Optomechanically-induced transparency (OMIT) and the associated slowing of light provide the basis for storing photons in nanoscale devices. Here we study OMIT in parity-time (PT)-…
