渐近广义扩展不确定原理

Asymptotic Generalized Extended Uncertainty Principle

Mariusz P. Dabrowski, Fabian Wagner

摘要:

我们提出了一种形式主义,允许微扰推导的扩展不确定原理(EUP)的任意空间曲率模型和观察员。进入小的位置不确定性的领域,我们推导出一个一般的渐近EUP。第二阶曲率引起的校正与里奇标量成比例,而第四阶校正的特征是0阶Cartan不变量Psi ^2(曲率张量的二次标量)和里奇标量的弯曲空间拉普拉斯算子,所有这些都是在位置算子的期望值处进行评估的,即在执行测量时的期望位置。这一结果首先验证了以前推导的均匀空间模型,然后适用于其他非平凡的曲率相关的影响,如不均匀性,旋转和各向异性应力流体导致黑洞“头发”。我们的主要成果结合了我们介绍的方法与广义不确定原理(GUP)凭借变形的分解,制定了一个通用的形式,我们称之为渐近广义扩展不确定原理(AGEUP)。

英文摘要:

We present a formalism which allows for the perturbative derivation of the Extended Uncertainty Principle (EUP) for arbitrary spatial curvature models and observers. Entering the realm of small position uncertainties, we derive a general asymptotic EUP. The leading 2nd order curvature induced correction is proportional to the Ricci scalar, while the 4th order correction features the 0th order Cartan invariant Psi^2 (a scalar quadratic in curvature tensors) and the curved space Laplacian of the Ricci scalar all of which are evaluated at the expectation value of the position operator, i.e. the expected position when performing a measurement. This result is first verified for previously derived homogeneous space models and then applied to other non-trivial curvature related effects such as inhomogeneities, rotation and an anisotropic stress fluid leading to black hole "hair". Our main achievement combines the method we introduce with the Generalized Uncertainty Principle (GUP) by virtue of deformed commutators to formulate a generic form of what we call the Asymptotic Generalized Extended Uncertainty Principle (AGEUP).
