全息测不准与中子星
Holographic indeterminacy and neutron stars
摘要:
由时空量子化产生的全息不确定性导致了两个事件的相对位置的固有不确定性(lpL)1/2,这两个事件之间的距离为L,在横向于连接事件的零射线的方向上,其中lP是普朗克长度。新的不确定性原理导致了一个临界条件,在该条件下,物体表面上两个直径相对的粒子的相对横向位置的全息不确定性变得大于物体中粒子之间的平均距离。重子质量和特征核密度是满足临界标准的重子体的最小质量和密度。因此,中子星被认为是全息不确定性可能产生物理后果的一类天体。
英文摘要:
The holographic indeterminacy resulting from the quantization of spacetime leads to an inherent uncertainty (lpL)1/2 in the relative positions of two events, separated by a distance L, in a direction transverse to a null ray connecting the events, where lP is the Planck length. The new indeterminacy principle leads to a critical condition in which the holographic uncertainty in the relative transverse positions of two diametrically opposed particles on the surface a body becomes greater than the average distance between particles in the body. The Chandrasekhar mass and the characteristic nuclear density emerge as the minimum mass and density of a baryonic body that could meet the critical criteria. Neutron stars are therefore identified as a class of bodies in which holographic indeterminacy may have physical consequences.
