Observation of coherent perfect absorption at an exceptional point
Changqing Wang, William R. Sweeney, A. Douglas Stone +1
The past few years have witnessed growing interests in exceptional points (EPs) in various domains, including photonics, acoustics and electronics. However, EPs have mainly been re…
Optomechanically Induced Transparency at Exceptional Points
Hao Lü, Changqing Wang, Lan Yang +1
We study optomechanically induced transparency in a microresonator coupled with nanoparticles. By tuning the relative angle of the nanoparticles, exceptional points (EPs) emerge pe…
Quantum Noise Theory of Exceptional Point Sensors
Mengzhen Zhang, William Sweeney, Chia Wei Hsu +3
Distinct from closed quantum systems, non-Hermitian system can have exceptional points (EPs) where both eigenvalues and eigenvectors coalesce. Recently, it has been proposed and de…
