To kill a quasiparticle: A quantum whodunit
Quasiparticles die young, lasting far, far less than a second. Why? A new Monash University study finds a culprit beyond the usual suspect (decay into lower energy states). Identification of the new villain--many-body dephasing--may be key to controlling quantum effects such as superconductivity and superfluidity.
