We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

The field of cavity optomechanics is reviewed. This field explores the interaction between
electromagnetic radiation and nanomechanical or micromechanical motion. This review …

Mechanical degrees of freedom, which have often been overlooked in various quantum
systems, have been studied for applications ranging from quantum information processing to …

By exploiting recent developments associated with coupled microcavities, we introduce the
concept of the PT-symmetric phonon laser with balanced gain and loss. This is …

Single photons with helical phase structures may carry a quantized amount of orbital
angular momentum (OAM), and their entanglement is important for quantum information …

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

The energy costs associated with separating tightly bound excitons (photoinduced electron-
hole pairs) and extracting free charges from highly disordered low-mobility networks …

We demonstrate PT-symmetry-breaking chaos in an optomechanical system, which features
an ultralow driving threshold. In principle, this chaos will emerge once a driving laser is …

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 …

Thermally induced fluctuations impose a fundamental limit on precision measurement. In
optical interferometry, the current bounds of stability and sensitivity are dictated by the …
