Analytical calculation of optical forces on spherical particles in optical tweezers: tutorial [PDF]
Journal of the Optical Society of America B, 2019 Recently, the Nobel prize in physics was awarded for the invention of optical tweezers. Thus far, they have been used as tools to obtain measurements of microscopic systems, mainly by harnessing the optical forces.

Negative optical torque on a microsphere in optical tweezers. [PDF]
Optics Express, 2019 We show that the optical force field in optical tweezers with elliptically polarized beams has the opposite handedness for a wide range of particle sizes and for the most common configurations.

Tilt control in optical tweezers [PDF]
Journal of Biomedical Optics, 2008 Laser trapping of micrometer-sized objects floating in water is investigated through the use of a tilted laser beam. With a change in the tilt direction, the orientation of the trapped object can be easily controlled when the object has an asymmetric body or nonuniform refractive index, such as nanowires, living cells, and so on.

Manipulating Ferroelectric Topological Polar Structures with Twisted Light
Advanced Materials, EarlyView.We demonstrate dynamic control of ferroelectric order in quasi‐2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non‐resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures.

Feasibility of Multiple Micro-Particle Trapping—A Simulation Study
Sensors, 2015 Both optical tweezers and acoustic tweezers have been demonstrated for trapping small particles in diverse biomedical applications. Compared to the optical tweezers, acoustic tweezers have deeper penetration, lower intensity, and are more useful in light

Direct observation of the effects of spin dependent momentum of light in optical tweezers
APL Photonics, 2020 We demonstrate that tight focusing of a circularly polarized Gaussian beam in optical tweezers leads to spin-momentum locking—with the transverse momentum density (Poynting vector) being helicity-dependent, while the transverse spin angular momentum ...
