In this paper, we derive the non-commutative corrections to the maximal acceleration of a massive particle. Using the eight-dimensional kappa-deformed phase-space metric, we obtain the kappa-deformed maximal acceleration, valid up to first order in the deformation parameter. We then derive the kappa-deformed geodesic equation and obtain its Newtonian limit and from this obtain a bound on the deformation parameter. After re-expressing the kappa-deformed Schwarzschild metric in terms of maximal acceleration, we analyse the motion of a particle in this space-time, and also study the modifications to Hawking radiation. We also derive the kappa-deformed corrections to maximal acceleration using kappa-deformed generalised uncertainty principle.

非交换时空的最大加速度及其含义

在本文中,我们导出了对大质量粒子最大加速度的非交换修正。使用八维 kappa 变形相空间度量,我们获得 kappa 变形的最大加速度,在变形参数中有效至一阶。然后我们推导出 kappa 变形测地线方程并获得其牛顿极限,并由此获得变形参数的界限。在根据最大加速度重新表达 kappa 变形的 Schwarzschild 度量后,我们分析了粒子在这个时空中的运动,并研究了对霍金辐射的修改。我们还使用 kappa 变形广义不确定性原理推导出了对最大加速度的 kappa 变形校正。
