متن کاملDetection of anisotropic particles in levitated optomechanics
Nanoparticles in optical traps are becoming increasingly interesting as they hold the promise of exploring quantum features at novel scales. Typical nanoparticles of mass 10−21 10−18 kg will push the classical-quantum boundary of exploration into the mesoscopic regime, improving by several orders on the mass 10−23 kg, which is the most massive object to have been shown to exhibit quantum interf...
متن کاملCavity optomechanics of levitated nanodumbbells: nonequilibrium phases and self-assembly.
Levitated nanospheres in optical cavities open a novel route to study many-body systems out of solution and highly isolated from the environment. We show that properly tuned optical parameters allow for the study of the nonequilibrium dynamics of composite nanoparticles with nonisotropic optical friction. We find optically induced ordering and nematic transitions with nonequilibrium analogs to ...
متن کاملAn analytical model for the detection of levitated nanoparticles in optomechanics.
Interferometric position detection of levitated particles is crucial for the centre-of-mass (CM) motion cooling and manipulation of levitated particles. In combination with balanced detection and feedback cooling, this system has provided picometer scale position sensitivity, zeptonewton force detection, and sub-millikelvin CM temperatures. In this article, we develop an analytical model of thi...
متن کاملOptimal Integral State Feedback Control of HCCI Combustion Timing
Homogenous Charge Compression Ignition (HCCI) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. But in contrast to gasoline and diesel engines, HCCI engines suffer from lack of having direct means to initiate combustion. A combustion timing controller with robust tracking performance is the key requirement to leverage HCCI application in production ...
