Laser loop couples quantum systems over a distance

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a great distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly ...

Coupled exploration of light and matter

n quasiparticles known as polaritons, states of light and matter are strongly coupled. The group of Prof. Ataç İmamoğlu has now developed a new approach to study nonlinear optical properties of polaritons in strongly correlated ...

Mirrors control chemical selectivity

A chemical reaction transforms the molecules that make up matter. To influence chemical reactions, chemists typically act on the molecules themselves, rather than the space in which the reaction takes places. However, researchers ...

Questions in quantum computing—how to move electrons with light

Electronics rely on the movement of negatively-charged electrons. Physicists strive to understand the forces that push these particles into motion, with the goal of harnessing their power in new technologies. Quantum computers, ...

Next up: Ultracold simulators of super-dense stars

Rice University physicists have created the world's first laser-cooled neutral plasma, completing a 20-year quest that sets the stage for simulators that re-create exotic states of matter found inside Jupiter and white dwarf ...

How photons change chemistry

The quantum nature of light usually does not play an important role when considering the chemical properties of atoms or molecules. In an article published in the Proceedings of the National Academy of Sciences scientists ...
