Dry launching of silica nanoparticles in vacuum
Ayub Khodaee, Kahan Dare, Aisling Johnson +2
Clean loading of silica nanoparticles with a radius as small as ~50 nm is required for experiments in levitated optomechanics that operate in ultra-high vacuum. We present a cheap…
Dissipative phase transitions in optomechanical systems
Fatemeh Bibak, Uroš Delić, Markus Aspelmeyer +1
We show that optomechanical quantum systems can undergo dissipative phase transitions within the limit of small nonlinear interaction and strong external drive. In such a defined t…
Force-Gradient Sensing and Entanglement via Feedback Cooling of Interacting Nanoparticles
Henning Rudolph, Uroš Delić, Markus Aspelmeyer +2
We show theoretically that feedback-cooling of two levitated, interacting nanoparticles enables differential sensing of forces and the observation of stationary entanglement. The f…
Observation of strong and tunable light-induced dipole-dipole interactions between optically levitated nanoparticles
Jakob Rieser, Mario A. Ciampini, Henning Rudolph +5
Arrays of optically trapped nanoparticles have emerged as a promising platform for the study of complex non-equilibrium phenomena. Analogous to atomic many-body systems, one of the…
