弯曲时空中Dirac场的一个绝对量子能量不等式

An absolute quantum energy inequality for the Dirac field in curved spacetime

Calvin J. Smith

摘要:

量子弱能量不等式(QWEI)是限制量子场的模糊重整化能量密度为负的程度的结果。在全局双曲时空中,大质量量子狄拉克场服从QWEI,其参考态是从阿达玛态类中任意选取的;然而,存在感兴趣的时空,其状态相关的边界不能被评估。本文证明了四维整体双曲时空上的大质量量子Dirac场的第一个QWEI,其中的界只依赖于局部几何;这样的QWEI被称为绝对QWEI。

英文摘要:

Quantum Weak Energy Inequalities (QWEIs) are results which limit the extent to which the smeared renormalised energy density of a quantum field can be negative. On globally hyperbolic spacetimes the massive quantum Dirac field is known to obey a QWEI in terms of a reference state chosen arbitrarily from the class of Hadamard states; however, there exist spacetimes of interest on which state-dependent bounds cannot be evaluated. In this paper we prove the first QWEI for the massive quantum Dirac field on four dimensional globally hyperbolic spacetime in which the bound depends only on the local geometry; such a QWEI is known as an absolute QWEI.
