Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown.

Researchers Find Clear Evidence For Coherent Phonons In Superlattices
2014-02-06 13:20:27

We all learn in high school science about the dual nature of light – that it exists as both waves and quantum particles called photons.

First-ever Bridge Between Optomechanics And Microfluidics Built By Researchers
2013-06-07 11:52:38

Researchers at the University of Illinois at Urbana-Champaign are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

Unprecedented Look At Quantum Oscillations Through Neutron Experiments

Size matters… but apparently so does shape – when it comes to conducting heat in very small spaces.

Laser Light Used To Cool Object To Quantum Ground State
2011-10-06 04:28:08

For the first time, researchers have managed to cool a miniature mechanical object to its lowest possible energy state using laser light.

Showcasing new tools for widespread development of quantum circuits made of mechanical parts, scientists from the National Institute of Standards and Technology (NIST) have demonstrated a flexible, broadly usable technique for steadily calming the vibrations of an engineered mechanical object down to the quantum "ground state," the lowest possible energy level.

Word of the Day
  • The abrogation of a law by a higher authority; annulment.
  • In music, during the eighteenth century, a song or an instrumental piece similar to the serenade, intended for performance in the open air.
The word 'cassation' comes from the French 'cassation', from Latin 'casso' ("destroy, annul").
