Optical levitation of dielectric particles in vacuum is a powerful technique for precision measurements, testing fundamental physics, and quantum information science. Conventional…
Femtosecond Laser Writing of Spin Defects in Hexagonal Boron Nitride
Xingyu Gao, Siddhant Pandey, Mehran Kianinia +5
Optically active spin defects in wide-bandgap materials have many potential applications in quantum information and quantum sensing. Spin defects in two-dimensional layered van der…
5D cooling and nonlinear dynamics of an optically levitated nanodumbbell
Jaehoon Bang, Troy Seberson, Peng Ju +5
Optically levitated nonspherical particles in vacuum are excellent candidates for torque sensing, rotational quantum mechanics, high-frequency gravitational wave detection, and mul…
Simulation of sympathetic cooling an optically levitated magnetic nanoparticle via coupling to a cold atomic gas
T. Seberson, Peng Ju, Jonghoon Ahn +3
A proposal for cooling the translational motion of optically levitated magnetic nanoparticles is presented. The theoretical cooling scheme involves the sympathetic cooling of a fer…
Ultrasensitive torque detection with an optically levitated nanorotor
Jonghoon Ahn, Zhujing Xu, Jaehoon Bang +3
Torque sensors such as the torsion balance enabled the first determination of the gravitational constant by Cavendish and the discovery of Coulomb's law. Torque sensors are also wi…
Stable emission and fast optical modulation of quantum emitters in boron nitride nanotubes
Jonghoon Ahn, Zhujing Xu, Jaehoon Bang +3
Atom-like defects in two-dimensional (2D) hexagonal boron nitride (hBN) have recently emerged as a promising platform for quantum information science. Here we investigate single-ph…
