… If the particles that emit spontaneous radiation are not scattered, but are strongly correlated for some reason and behave in unison, the lifetime of the spontaneous emission is significantly shortened and powerful light is emitted. This is called superradiance. When N particles are perfectly correlated, the lifetime is reduced to 1/ N , and the light intensity is N 2 times the emission intensity from a single particle ( N times that of normal spontaneous emission). … *Some terminology explanations that mention "superradiance" are listed below.

… 自然放出を行う粒子が,ばらばらではなく,何らかの原因によって強い相関を生じて足並みそろえたふるまいをすると,自然放出の寿命は著しく短縮され,強力な光を放出する。これを超放射superradianceという。N個の粒子が完全な相関をもつと,寿命はN分の1になり,光強度は1粒子からの発光強度のN2倍になる(ふつうの自然放出ではN倍)。… ※「superradiance」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
