A trio of physicists with Columbia University is making waves with a new theory about phonons—they suggest they might have negative mass, and because of that, have negative gravity. Angelo Esposito, Rafael Krichevsky and ...
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Physicists have explored this analogy in recent experimental ...
Ultrashort light-pulse-induced vibrations of atoms in a lattice, called optical coherent phonons, have been controlled in various materials. However, different experiments demonstrating such control have been explained through ...
