A quasi-mode theory of chiral phonons
Xunnong Xu, Seunghwi Kim, Gaurav Bahl +1
The coherence properties of mechanical resonators are often limited by multiple unavoidable forms of loss -- including phonon-phonon and phonon-defect scattering -- which result in…
Dynamically induced robust phonon transport and chiral cooling in an optomechanical system
Seunghwi Kim, Xunnong Xu, Jacob M. Taylor +1
The transport of sound and heat, in the form of phonons, can be limited by disorder-induced scattering. In electronic and optical settings the introduction of chiral transport, in…
Cooling a harmonic oscillator by optomechanical modification of its bath
Xunnong Xu, Thomas Purdy, Jacob M. Taylor
Optomechanical systems show tremendous promise for high sensitivity sensing of forces and modification of mechanical properties via light. For example, similar to neutral atoms and…
Partially dark optical molecule via phase control
Z. H. Wang, Y. Li
We study the tunable photonic distribution in an optical molecule consisting of two linearly coupled single-mode cavities. With the inter-cavity coupling and two driving fields, th…
Phonon blockade in a nanomechanical resonator resonantly coupled to a qubit
Xun-Wei Xu, Ai-Xi Chen, Yu-xi Liu
We study phonon statistics in a nanomechanical resonator (NAMR) which is resonantly coupled to a qubit. We find that there are two different mechanisms for phonon blockade in such…
