Cooling of an Optically Levitated Nanoparticle via Measurement-Free Coherent Feedback Open
We demonstrate coherent, measurement-free optical feedback control of a levitated nanoparticle, achieving phonon occupations down to a few hundred phonons. Unlike measurement-based feedback, this all-optical scheme preserves the correlatio…

Accelerated State Expansion of a Nanoparticle in a Dark Inverted Potential Open
While the wave packet of a massive particle grows linearly under free dynamics, it grows exponentially in an inverted harmonic potential, offering a pathway to rapidly increase quantum fluctuations to macroscopic dimensions. In this work, …
