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

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, trap**, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work …

Methods for controlling the motion of single particles, optically levitated in vacuum, have
developed rapidly in recent years. The technique of cold dam** makes use of feedback …

Intense light traps and binds small particles, offering unique control to the microscopic world.
With incoming illumination and radiative losses, optical forces are inherently …

We demonstrate all-optical sympathetic cooling of a laser-trapped microsphere to sub-Kelvin
temperatures, mediated by optical binding to a feedback-cooled adjacent particle. Our study …

Realizing a large-scale fully controllable quantum system is a challenging task in current
physical research and has broad applications. In this work, we create a reconfigurable …

We explore, experimentally and theoretically, the emergence of coherent coupled
oscillations and synchronization between a pair of non-Hermitian, stochastic, opto …

Recent experiments demonstrate highly tunable nonreciprocal coupling between levitated
nanoparticles due to optical binding [J. Rieser, Science 377, 987 (2022) 0036-8075 …

Feedback control can be used to generate well-determined nonlinear effective potentials in
an optical trap, a goal whose applications may range from nonequilibrium thermodynamics …
