2. In superfluorescence, electrical charges known as dipoles emit light in
synchronized bursts so intense that they are visible to the eye. Until recently, this
phenomenon has only been observed at extremely cold temperatures because
dipoles cannot synchronize at higher temperatures. But in a study, Melike Biliroglu
and colleagues observed superfluorescence at room temperature in thin films
made of perovskite and other similarly crystalline materials; the researchers
propose that the formation of shock-absorbing quasiparticles called polarons in
the material protects dipoles from thermal interference.
Based on the text, how are polarons believed to be involved in the
superfluorescence observed in Biliroglu and colleagues' study?
Polarons enable superfluorescent bursts to cross from one crystalline material to
another.
Polarons allow for the dipoles to synchronize despite higher temperatures.
Polarons accelerate the dipoles' release of superfluorescent bursts.
Polarons decrease the intensity of the superfluorescent burst.
