Quantum Physics


Light Spectrum Identify Molecules

Authors: George Rajna

Researchers have built a new tool to study molecules using a laser, a crystal and light detectors. [19] By hitting electrons with an ultra-intense laser, researchers have revealed dynamics that go beyond 'classical' physics and hint at quantum effects. [18] The phenomenon of ionic wind has been known about for centuries: by applying a voltage to a pair of electrodes, electrons are stripped off nearby air molecules, and the ionized air collides with neutral air molecules as it moves from one electrode to the other. [17] A small group of physicists from the Israel Institute of Technology and the Institute for Pure and Applied Mathematics (IMPA) in Brazil have now come up with another method, showing it's theoretically possible to weave waves of light together in such a way that they stop dead in their tracks.
