Propulsive effects of light, which often remain unnoticed in our daily-life experience, manifest
themselves on spatial scales ranging from subatomic to astronomical. Light-mediated forces …

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 binding is a laser-induced inter-particle force that exists between two or more
particles subjected to off-resonant light. It is one of the key tools in optical manipulation of …

The creation of optically powered self-assembling nano-to-meso-scale machines that do
work is a long-standing goal in photonics. We demonstrate an optical matter (OM) machine …

Optical printing holds great potential to enable the use of the vast variety of colloidal
nanoparticles (NPs) in nano-and microdevices and circuits. By means of optical forces, it …

Optically levitated nanoparticles in a vacuum offer a light–matter interface with broad and
easy tunability of all key system parameters. However, the majority of previously reported …

Silicon nanowires are held and manipulated in controlled optical traps based on counter-
propagating beams focused by low numerical aperture lenses. The double-beam …

Optical binding allows creation of mechanically stable nanoparticle configurations owing to
formation of self-consistent optical trap** potentials. While the classical diffraction limit …

T-matrix methods for electromagnetic structured beams mainly encompass Generalized
Lorenz-Mie Theories (GLMTs) which form a set of analytical approaches dealing with the …

Among the many works of Arthur Ashkin, many have been devoted to optical tweezers,
optical levitation and optical manipulation of macroscopic particles (“macroscopic” being …
