弯曲时空中QFT的薛定谔形式的么正性

Unitarity in the Schroedinger Formalism of QFT in Curved Space-Time

Patrick Hager, Maximilian Urban

摘要:

本文回顾了弯曲时空中标量场的薛定谔量子化,并讨论了基态的确定。通过显式地计算基态波泛函的范数,我们证明了半经典Bianchi-Ⅰ型时空中QFT基态的不稳定性。我们发现,这个规范是,在一般情况下,时间依赖性,并得出结论,基态演化不是单一的。

英文摘要:

We review the general quantization of scalar fields in curved space-times in the Schroedinger formalism and discuss the determination of the ground-state. By explicitly computing the norm of the ground-state wave functional, we give an argument for the instability of the ground-state of a QFT in a semi-classical space-time of Bianchi-type I. We find that this norm is, in general, time-dependent, and conclude that the ground-state evolution is not unitary.
