The ability to create phonons and then steer them using laser beams could lead to a new generation of applications, say physicists Zap an optical fibre with a couple of laser beams and the resulting interference pattern causes an interesting effect–it squeezes the material, an effect known as electrostriction. This creates a compression wave called […]

Physicists worldwide were celebrating an elusive thing called the Higgs Boson, which had apparently made a brief appearance. They kept repeating that it was important because it gives matter mass, but […]
