New study shows nanoscale pendulum coupling

In 1665, Lord Christiaan Huygens found that two pendulum clocks, hung in the same wooden structure, oscillated spontaneously and perfectly in line but in opposite directions: the clocks oscillated in anti-phase. Since then, ...

Controlling on-chip nano-optics by graphene nano-opto-mechanics

Active in situ control of light at the nanoscale remains a challenge in modern physics and in nanophotonics in particular. A promising approach is to take advantage of the technological maturity of nanoelectromechanical systems ...

Cooling massive objects to the quantum ground state

Ground state cooling of massive mechanical objects remains a difficult task restricted by the unresolved mechanical sidebands. Now researchers have proposed an optomechanically-induced-transparency cooling scheme to achieve ...
