局部协变量子场论

Aspects of locally covariant quantum field theory

Ko Sanders

摘要:

本论文考虑了局部协变量子场论(LCQFT;见Brunetti等人,237(2003),31-68),描述弯曲时空中的公理化量子场论的数学框架。新的成果包括:用模态逻辑对这一理论框架的某些方面作了哲学解释,证明了自由实标量场的任何Hadamard态的截断n点函数都是光滑的(n=2除外),用表示无关的方法描述了自由Dirac场,表明该理论完全由伴随映射、电荷共轭映射和Dirac算子之间的关系决定;证明了自由狄拉克场的相对柯西演化与其应力-能量-动量张量的关系与自由实标量场的关系相同(参见loc.cit.);几个结果的Reeh-Schlieder属性LCQFT,包括但不限于我们以前的文件;一个新的和优雅的方法,波前集的Banach空间值分布,它允许容易的证明和文献中的结果的扩展。

英文摘要:

This thesis considers various aspects of locally covariant quantum field theory (LCQFT; see Brunetti et al., Commun.Math.Phys. 237 (2003), 31-68), a mathematical framework to describe axiomatic quantum field theories in curved spacetimes. New results include: a philosophical interpretation of certain aspects of this framework in terms of modal logic; a proof that the truncated n-point functions of any Hadamard state of the free real scalar field are smooth, except for n=2; a description of he free Dirac field in a representation independent way, showing that the theory is determined entirely by the relations between the adjoint map, the charge conjugation map and the Dirac operator; a proof that the relative Cauchy evolution of the free Dirac field is related to its stress-energy-momentum tensor in the same way as for the free real scalar field (cf. loc.cit.); several results on the Reeh-Schlieder property in LCQFT, including but not limited to those of our earlier paper; a new and elegant approach to wave front sets of Banach space-valued distributions, which allows easy proofs and extensions of results in the literature.
