彎曲時空中的量子場論

粒子物理學中,彎曲時空的量子場論是指將平直時空量子場論推展到彎曲時空。此理論的一般性預測為:重力場或具有視界的非時變重力場皆可導致粒子創生

應用编辑

此理論最令人嘖嘖稱奇的應用為霍金輻射,指出黑洞帶有黑體輻射。另一個相關的預測為盎魯效應,指出加速中的觀察者可以觀測到真空中出現粒子的熱浴,這在慣性觀察者是觀察不到的。

此外,宇宙暴脹造成的太初密度微擾也可以之計算,而實驗上也可透過天文學觀測(例如宇宙背景輻射)來驗證。

狄拉克方程式也可有彎曲時空中的形式,參見彎曲時空中的狄拉克方程

量子重力的近似编辑

彎曲時空中的量子場論也可以視作量子重力的初階近似。更進一步的理論為半古典重力,其考慮了強重力場所造成的粒子創造;此理論仍屬古典理論,並且等效原理仍然適用。廣義相對論所描述的重力,其不可重整化特性是將重力量子化的主要障礙。[1]
