: Light forces can be harnessed to levitate mesoscopic objects and cool them down towards their motional quantum ground state. Significant roadblocks on the way to scale up levitation from a single to multiple particles in close proximity are the requirements to constantly monitor the particles’ positions as well as to engineer complex light fields that react fast and appropriately to their movements. Here, we present an approach that solves both problems at once. By exploiting the information…

Optimal Cooling of Multiple Levitated Particles: Theory of Far-Field Wavefront-Shaping

The opportunity to manipulate small-scale objects pushes us to the limits of our understanding of physics. Particularly promising in this regard is the interdisciplinary field of levitation, in which

Cavity Cooling of a Levitated Nanosphere by Coherent Scattering.

By achieving nanometer-level control over the particle location, this work optimize the position-dependent coupling and demonstrate axial cooling by two orders of magnitude at background pressures of 6×10^{-2}  mbar.

Optical binding of two cooled micro-gyroscopes levitated in vacuum

Coupling between mesoscopic particles levitated in vacuum is a prerequisite for the realization of a large-scale array of particles in an underdamped environment as well as potential studies at the

Optimal wave fields for micromanipulation in complex scattering environments

By designing wavefronts in the far field that have optimal properties in the near field, a general framework for optimal micromanipulation with targets of arbitrary shape and in arbitrarily complex environments, such as disordered media, is reported.

Cavity-Based 3D Cooling of a Levitated Nanoparticle via Coherent Scattering.

C cavity cooling of all three translational degrees of motion of a levitated nanoparticle in vacuum is experimentally realized and it is found that the cooling efficiencies depend on the particle position within the intracavity standing wave.

Quantum control of a nanoparticle optically levitated in cryogenic free-space

Tests of quantum mechanics on a macroscopic scale require extreme control over mechanical motion and its decoherence [1-4]. Quantum control of mechanical motion has been achieved by engineering the

Optomechanics with levitated particles

Optomechanics is concerned with the use of light to control mechanical objects, and trapped mesoscopic particles are the paradigmatic system for studying nanoscale stochastic processes, and have already demonstrated their utility in state-of-the-art force sensing.

Wavefront shaping in complex media with a 350 kHz modulator via a 1D-to-2D transform

Controlling the propagation and interaction of light in complex media has sparked major interest in the past few years. Unfortunately, spatial light modulation devices suffer from limited speed,

Cold Damping of an Optically Levitated Nanoparticle to Microkelvin Temperatures.

For the first time, the imprecision-backaction product for a levitated optomechanical system is determined and the resulting implications for ground-state cooling of an optically levitated nanoparticle are discussed.

Zeptonewton force sensing with nanospheres in an optical lattice

Optically trapped nanospheres in high vacuum experience little friction and hence are promising for ultrasensitive force detection. Here we demonstrate measurement times exceeding ${10}^{5}$ s and
