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的量子場論推展到彎曲時空。此理論的一般性預測為：時變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]此理論最著名的應用為霍金輻射，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]
