In billions of years’ time, once our sun has used up all its fuel and puffed up to become a red giant before throwing off layers to form a planetary nebula, all that will remain at its heart is a ...
Fadel’s group created a state in which the crystal contained a superposition of a single phonon and zero phonons. “In a sense, the crystal is in a state where it is still and vibrating at the same time,” says Fadel. ...
