Optomechanical Levitation and Control of High Aspect Ratio Silicon Nanorods
Zhenan Chen, Sophie Sanghera, Yanhui Hu +7
Nano- and micro-particles levitated by optical, electrical or magnetic fields are a new frontier in precision sensing and for tests of fundamental physics. For optically levitated…
A Levitated Random Telegraph Noise Spectrometer
Molly Message, Bianca C. J. Uy, Katie O'Flynn +7
Random Telegraph Noise is a ubiquitous process manifesting across technology and the natural world. It is characterized by random jumps between two distinct states with Poissonian…
Talking with a ghost: semi-virtual coupled levitated oscillators
Ronghao Yin, Yugang Ren, Deok Young Seo +4
Mesoscopic particles levitated by optical, electrical or magnetic fields act as mechanical oscillators with a range of surprising properties, such as tuneable oscillation frequenci…
Extreme-temperature single-particle heat engine
Molly Message, Federico Cerisola, Jonathan D. Pritchett +5
There are many exotic thermodynamic processes that are hard to study in nature. Here, we synthesize a structured environment to explore the extremes of thermodynamics. We present a…
Neuromorphic detection and cooling of microparticles in arrays
Yugang Ren, Benjamin Siegel, Ronghao Yin +4
Micro-objects levitated in a vacuum are an exciting platform for precision sensing due to their low dissipation motion and the potential for control at the quantum level. Arrays of…
Using optical tweezers to simultaneously trap, charge and measure the charge of a microparticle in air
Andrea Stoellner, Isaac C. D. Lenton, Artem G. Volosniev +9
Optical tweezers are widely used as a highly sensitive tool to measure forces on micron-scale particles. One such application is the measurement of the electric charge of a particl…
