全息量子几何的不确定性

Indeterminacy of Holographic Quantum Geometry

Craig J. Hogan

摘要:

利用基于波动光学的有效理论,描述了普朗克尺度下紫外截止全息时空中的位置不确定性。描述时空位置的波函数被建模为准单色辐射的复杂扰动。证明了全息光片平面内两个位置波函数的标准偏差的乘积等于它们的法向间距与普朗克长度的乘积。对于宏观分离的位置,横向不确定性远大于普朗克长度,并且被预测为相对位置上的“全息噪声”,具有独特的剪切空间特征,并且一旦从引力热力学理论确定基本波长,就可以观察到绝对归一化的频谱,没有参数。全息噪声的频谱估计的GEO600干涉引力波探测器,并示出约占目前无法解释的噪声之间的约300和1400赫兹。在全息世界中,这个结果直接而精确地测量了基本的最小时间间隔。

英文摘要:

An effective theory based on wave optics is used to describe indeterminacy of position in holographic spacetime with a UV cutoff at the Planck scale. Wavefunctions describing spacetime positions are modeled as complex disturbances of quasi-monochromatic radiation. It is shown that the product of standard deviations of two position wavefunctions in the plane of a holographic light sheet is equal to the product of their normal separation and the Planck length. For macroscopically separated positions the transverse uncertainty is much larger than the Planck length, and is predicted to be observable as a "holographic noise" in relative position with a distinctive shear spatial character, and an absolutely normalized frequency spectrum with no parameters once the fundamental wavelength is fixed from the theory of gravitational thermodynamics. The spectrum of holographic noise is estimated for the GEO600 interferometric gravitational-wave detector, and is shown to approximately account for currently unexplained noise between about 300 and 1400Hz. In a holographic world, this result directly and precisely measures the fundamental minimum interval of time.
