LIGHTING A FIRE WITH VACUUM FRICTION
ONE OF THE SURPRISES OF QUANTUM MECHANICS IS ZERO POINT FLUCTUATIONS WHICH PERVADE BOTH VACUUM AND MATTER. Far from just theoretical interest, practical consequences exist at the nanoscale when these fluctuations cause forces that attract or repel macroscopic bodies. They are also manifested at the...
MOVING PLATES CREATE NEGATIVE-FREQUENCY PHOTONIC RESONANCE
When in relative motion, plates of a Fabry-Perot interferometer generate a unique resonance with negative frequency if separated by a gap of critical size. We commonly encounter the idea of negative frequencies while analyzing electromagnetic waves and signals, which are often helpful as a...
TRAPPING LIGHT THAT DOESN’T BOUNCE OFF TRACK FOR FASTER ELECTRONICS
WEST LAFAYETTE, Ind. — Replacing traditional computer chip components with light-based counterparts will eventually make electronic devices faster due to the wide bandwidth of light. A new protective metamaterial "cladding" prevents light from leaking out of the very curvy pathways it would travel...
CONTROLLING FORCES BETWEEN ATOMS, PROMISING FOR ‘2-D HYPERBOLIC’ MATERIALS
A new approach to control forces and interactions between atoms and molecules, such as those employed by geckos to climb vertical surfaces, could bring advances in new materials for developing quantum light sources. “Closely spaced atoms and molecules in our environment are constantly interacting...
