# phys: oscillating quasiparticles, decay and rebirth

<< Admittedly, quasiparticles do decay, however new, identical particle entities emerge from the debris," (..) If this decay proceeds very quickly, an inverse reaction will occur after a certain time and the debris will converge again. This process can recur endlessly and a sustained oscillation between decay and rebirth emerges. >> Ruben Verresen.
