场混合中Unruh效应的非热特征

Non-thermal signature of the Unruh effect in field mixing

Massimo Blasone, Gaetano Lambiase, Giuseppe Gaetano Luciano

摘要:

在量子场论框架内分析了匀加速观测器(Rindler观测器)的混合变换,作为研究引力对味振荡影响的基础。特别地,讨论了两个不同质量的带电玻色子场的情况。尽管有这样一个最小的设置,标准的Unruh辐射被发现松动其特征的热解释,由于之间的相互作用的Bogolubov变换隐藏在现场混合和所产生的一个从林德勒时空结构。在小质量差的极限下,计算了Rindler观测器观测到的修正谱。

英文摘要:

Mixing transformations for a uniformly accelerated observer (Rindler observer) are analyzed within the quantum field theory framework as a basis for investigating gravitational effects on flavor oscillations. In particular, the case of two charged boson fields with different masses is discussed. In spite of such a minimal setting, the standard Unruh radiation is found to loose its characteristic thermal interpretation due to the interplay between the Bogolubov transformation hiding in field mixing and the one arising from the Rindler spacetime structure. The modified spectrum detected by the Rindler observer is explicitly calculated in the limit of small mass difference.
