Rindler空间类时超曲面上的量子场论

Quantum field theory on timelike hypersurfaces in Rindler space

Daniele Colosi, Dennis Rätzel

摘要:

将量子场论的一般边界公式应用于二维Rindler空间中的大质量标量场。根据薛定谔-费曼量子化公式和全纯量子化公式,场在两个不同的时空区域中被量子化:一个由两个柯西曲面限定的区域和一个由一条类时曲线限定的区域。一个同构之间的希尔伯特空间构造与这两个边界。这种同构保持了可以从自由和相互作用量子场论中提取的概率,证明了在两种设置中定义的S矩阵的等价性,当两者都适用时。

英文摘要:

The general boundary formulation of quantum field theory is applied to a massive scalar field in two dimensional Rindler space. The field is quantized according to both the Schrödinger-Feynman quantization prescription and the holomorphic one in two different spacetime regions: a region bounded by two Cauchy surfaces and a region bounded by one timelike curve. An isomorphism is constructed between the Hilbert spaces associated with these two boundaries. This isomorphism preserves the probabilities that can be extracted from the free and the interacting quantum field theories, proving the equivalence of the S-matrices defined in the two settings, when both apply.
