Microscopic Control and Detection of Ultracold Strontium in Optical-Tweezer Arrays

Physical Review X, 2018
Optical tweezers provide a versatile platform for the manipulation and detection of single atoms. Here, we use optical tweezers to demonstrate a set of tools for the microscopic control of atomic strontium, which has two valence electrons.

Influence of Laser Intensity Fluctuation on Single-Cesium Atom Trapping Lifetime in a 1064-nm Microscopic Optical Tweezer

Applied Sciences, 2020
An optical tweezer composed of a strongly focused single-spatial-mode Gaussian beam of a red-detuned 1064-nm laser can confine a single-cesium (Cs) atom at the strongest point of the light intensity.

Printing and Rerouting of Elastic and Protease Responsive Shape Memory Hydrogel Filaments

Advanced Healthcare Materials, EarlyView.
A biofabrication strategy, Rerouting of Free‐Floating Suspended Hydrogel Filaments (REFRESH), is developed enabling the printing of highly elastic, reconfigurable protease‐responsive hydrogel filaments with shape memory properties. The filaments can be manually braided, knotted, and rerouted to create intricate cell‐laden 3D architectures, expanding ...

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.

On chip shapeable optical tweezers [PDF]

Scientific Reports, 2013
Particles manipulation with optical forces is known as optical tweezing. While tweezing in free space with laser beams was established in the 1980s, integrating the optical tweezers on a chip is a challenging task. Recent experiments with plasmonic nanoantennas, microring resonators, and photonic crystal nanocavities have demonstrated optical trapping.

Superior Adhesion of Monolayer Amorphous Carbon to Copper

Advanced Materials, EarlyView.
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...
