Inverse Microparticle Design for Enhanced Optical Trapping and Detection Efficiency in All Six Degrees of Freedom
Achieving quantum-limited motional control of optically trapped particles beyond the sub-micrometer scale is an outstanding problem in levitated optomechanics. A key obstacle is solving the light scattering problem and identifying particle geometries that allow stable trapping and efficient motional detection of their center of mass and rotational motion in three dimensions. Here, we present a computational framework that combines an efficient electromagnetic scattering solver with the adjoint …

Removal of Lunar Dust Simulant from Cold Dielectric Surfaces with Electron Beam
It has been demonstrated that lunar dust simulant can be efficiently lofted and removed from various room temperature surfaces in vacuum when exposed to a low-energy electron beam. This provides a potential solution to the well-known dust risks associated with future lunar exploration. Considering its application in extremely cold regions on the Moon, we experimentally demonstrated dust lofting from surfaces at temperatures as low as -123degC using an electron beam. Compared to room temperature…

Magnetic Dipole Trapping Potential between Infinite Superconducting Plates
We derive the exact analytic form of the potential experienced by a magnetic dipole trapped between two infinite parallel superconducting plates using the method of image dipoles, providing a benchmark for numerical methods and a foundation for studying the stability and dynamics of magnetically levitated systems in precision measurements and fundamental physics experiments.
