Optical trapping describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trapping with a single beam, this is …

BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

Tests of quantum mechanics on a macroscopic scale require extreme control over
mechanical motion and its decoherence,–. Quantum control of mechanical motion has been …

The ability to accurately control the dynamics of physical systems by measurement and
feedback is a pillar of modern engineering. Today, the increasing demand for applied …

Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

The quantum ground state of a massive mechanical system is a stepping stone for
investigating macroscopic quantum states and building high fidelity sensors. With the recent …

Arrays of optically trapped nanoparticles have emerged as a platform for the study of
complex nonequilibrium phenomena. Analogous to atomic many-body systems, one of the …

Optical tweezers are tools made of light that enable contactless pushing, trapping, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work …

Gravity is the weakest of all known fundamental forces and poses some of the most
important open questions to modern physics: it remains resistant to unification within the …

Dynamical backaction resulting from radiation pressure forces in optomechanical systems
has proven to be a versatile tool for manipulating mechanical vibrations. Notably, dynamical …
