Quantum leap for phonon lasers

Âé¶¹ÒùÔºicists have taken major step forward in the development of practical phonon lasers, which emit sound in much the same way that optical lasers emit light. The development should lead to new, high-resolution imaging devices ...

Âé¶¹ÒùÔºicists Propose a Method to Observe Dirac Monopoles

(Âé¶¹ÒùÔºOrg.com) -- For decades, scientists have been intrigued by the hypothetical existence of magnetic monopoles - particles with only a north or south magnetic pole, thus having a nonzero magnetic charge. But while modern ...

Researchers putting a freeze on oscillator vibrations

University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical ...
