Dual-mode ground-state cooling in quadratic optomechanical systems: from multistability to general dark-mode suppression
Huanhuan Wei, Yun Chen, Jing Tang +1
We theoretically investigate a quadratic optomechanical system comprising a single-mode optical cavity linearly coupled to one mechanical resonator and quadratically coupled to a s…

Cell-Dependent Criticality for Quantum Metrology
Zhoutao Lei, Jihao Ma, Yun Chen +2
Exploiting enhanced sensitivity of a system in the vicinity of a phase transition boundary, critical quantum metrology to date still suffers from gap-closure related bottleneck eff…

Chirality-Induced Orbital-Angular-Momentum Selectivity in Electron Transmission and Scattering
Yun Chen, Oded Hod, Joel Gersten +1
Chirality-induced orbital-angular-momentum selectivity (CIOAMS) in electron transmission and scattering processes is investigated. Polarization of the OAM of an electron traversing…
