Ultrastrong linear optomechanical interaction Open
Light-matter interaction in the ultrastrong coupling regime can be used to generate exotic ground states with two-mode squeezing and may be useful for quantum-enhanced sensing. Current demonstrations of ultrastrong coupling have been perfo…

Dry launching of silica nanoparticles in vacuum Open
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 and simple experimental method for dry launching of silica …

Cooling of a levitated nanoparticle to the motional quantum ground state Open
A nanoparticle trapped and cooled Cooling massive particles to the quantum ground state allows fundamental tests of quantum mechanics to be made; it would provide an experimental probe of the boundary between the classical and quantum worl…

Cooled to the Quantum Realm Open
One of the biggest questions of our time is how gravity and quantum mechanics interact. We have achieved a long-sought-after step towards this goal by laser cooling a solid object. - submission by Kahan Dare, Manuel Reisenbauer, Uroš Delić

Motional Quantum Ground State of a Levitated Nanoparticle from Room Temperature Open
We report quantum ground state cooling of a levitated nanoparticle in a room temperature environment. Using coherent scattering into an optical cavity we cool the center of mass motion of a $143$ nm diameter silica particle by more than $7…

An adaptable dual species effusive source and Zeeman slower design demonstrated with Rb and Li Open
We present a dual-species effusive source and Zeeman slower designed to produce slow atomic beams of two elements with a large mass difference and with very different oven temperature requirements. We demonstrate this design for the case o…

Tools for trapping and detecting ultracold gases Open
We construct a vertical imaging system designed to image along the quantization axis of the experiment. We demonstrate that it has a resolution on the order of 1-2μm which is on par with previous characterizations of the constituent compon…
