一般时空中的有效量子场论

Effective quantum field theories in general spacetimes

Andreas Raab

摘要:

我们引入规则图作为时空中的物理参考系,并证明了一般时空总是可以被规则图完全捕获。有效的量子场论可以方便地定义在正则参考系中,并且定义与特定的背景度量无关,也与特定的正则参考系无关。因此,耦合到经典引力是可能的,在有效的QFT没有得到反反应效应。此外,我们提出了一种有效的QFT包括量子引力的方法。

英文摘要:

We introduce regular charts as physical reference frames in spacetime, and we show that general spacetimes can always be fully captured by regular charts. Effective quantum field theories (QFTs) can be conveniently defined in regular reference frames, and the definition is independent of specific background metric and independent of specific regular reference frame. As a consequence, coupling to classical gravity is possible in effective QFTs without getting back-reaction effects. Moreover, we present an approach to effective QFTs including quantum gravity.
