在几何相对论理论中模拟量子理论轨道

Modelling Quantum Theoretical Trajectories within Geometric Relativistic Theories

Mike Stannett

摘要:

Andreka和她的同事们描述了各种受几何启发的狭义相对论和广义相对论的一阶理论,而Szekely的博士论文则专注于加速观察者的中间逻辑。在本文中,我们将尝试将一个模型的量子理论轨迹,可以合理地声称是物理意义到这些理论。我们最近已经证明,当时空假设为欧几里德时,基于离散有限运动的量子轨道模型在逻辑上等价于费曼的路径积分公式。在本文中,我们认为,相对论的观察者受到相同的量子错觉,在欧几里德的情况下:即使运动是离散的,不尊重内置的“时间之箭”,观察者别无选择,只能感知粒子的轨迹作为连续的路径在时空中。相对论性理论把连续路径作为公理的一部分,而连续性的错觉使我们能够用一个关于时空中离散跳跃的较低层次的量子启发公理来取代这一公理。我们研究这些跳跃的性质,以及它们与时空的基本几何结构有多大的联系。特别是,我们认为保持功能的基础数字字段的跳,并调查在何种程度上可以限制所有的跳是这种形式。我们的结论是,基于跳跃的运动也可以被视为一种错觉,一个在“错误”的数字系统中建模物理造成的。

英文摘要:

Andreka and her colleagues have described various geometrically inspired first-order theories of special and general relativity, while Szekely's PhD dissertation focuses on an intermediate logic of accelerated observers. In this paper we will attempt to incorporate a model of quantum theoretical trajectories that can reasonably claim to be physically meaningful into those theories. We have recently shown that a model of quantum trajectories, based on discrete finitary motion, is logically equivalent to Feynman's path-integral formulation when spacetime is assumed to be Euclidean. In this paper we argue that relativistic observers are subject to the same quantum illusions as in the Euclidean case: even though motion is discrete and respects no built-in 'arrow of time', observers have no choice but to perceive particle trajectories as continuous paths in spacetime. Whereas the relativistic theories presuppose continuous paths as part of their axioms, the illusion of continuity allows us to replace this axiom with a lower-level quantum-inspired axiom concerning discrete jumps in spacetime. We investigate the nature of these jumps, and how far they can be tied to the underlying geometric structure of spacetime. In particular, we consider hops which preserve features of the underlying number field, and investigate the extent to which all hops can be restricted to be of this form. We conclude that hop-based motion can also be regarded as an illusion, one caused by modelling physics in the 'wrong' number system.
