How molecules interact with a laser field

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin ...

Electronically programmable photonic molecule

Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. Artificial atom-like and molecule-like systems were previously demonstrated to regulate light ...

Twisting light to enable high-capacity data transmission

For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used ...

Self-healing electroluminescent (EL) devices

In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that ...

Researchers design technology that sees nerve cells fire

Scientists have plenty of ways to watch as individual neurons in a brain fire, sending electrical signals from one to the next, but they all share a basic problem. Each method, whether it involves electrical probes, chemical ...

Networking goes quantum

A scientist involved in expanding quantum communication to a network of users, is continuing his work at the University of Bristol.

New discovery improves use of optical tweezers

This year's Nobel Prize in Physics, awarded for discoveries in laser physics, recognizes optical tweezers. Now researchers from the University of Gothenburg have developed a method that greatly simplifies and improves the ...

New method gives microscope a boost in resolution

Scientists at the University of Würzburg have been able to boost current super-resolution microscopy by a novel tweak. They coated the glass cover slip as part of the sample carrier with tailor-made biocompatible nanosheets ...
