We report on the realization of large assembled arrays more than 300 single $^{87}$Rb atoms trapped in optical tweezers a cryogenic environment at $\sim4$~K. For with $N_{\rm a}=324$ atoms, assembly process results defect-free $\sim37\%$ realizations. To achieve this high assembling efficiency, we equalize loading probability traps within array using closed-loop optimization power each tweezers...

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have become an essential tool several fields of physics, spectroscopy, biology, nanotechnology, thermodynamics. In this tutorial, we provide a primer on how to calibrate use them for advanced applications. After brief general introduction tweezers, focus describing comparing the various available calibration techniq...

Single-particle tracking and optical tweezers are powerful techniques for studying diverse processes at the microscopic scale. The stochastic behavior of a particle contains information about its interaction with surrounding molecules, an tweezer can further facilitate this observation ability to constrain area interest. Although these found their initial applications in biology, they also shed...

Enabled by multiple optical traps, holographic tweezers can manipulate particles in parallel flexibly. Spatial light modulators are widely used tweezers, which Gaussian point (GP) trap arrays or special mode including vortex (OV) arrays, perfect (PV) and Airy beam etc., be generated addressing various phase holograms. However, the traps these almost all of same type. Here, we propose a new meth...

Optoelectronic tweezers (OET) is a new tool for noninvasive, parallel manipulation of cells and/or micro/nanoparticles. Based on light-induced dielectrophoresis, OET can trap and sort colloidal particles, biological cells, nanowires and nanoparticles using a digital light projector. In this paper, we will present the principle and recent experimental results of OET. Keywords-Optoelectronic twee...
