有界区域上的Bohmian经典极限

Bohmian Classical Limit in Bounded Regions

Davide Romano

摘要:

玻姆力学是对量子理论的实在论解释。它与经典力学有着相同的本体论:粒子在时空中沿着连续的轨迹运动。对于这种本体论的连续性,它似乎是恢复量子理论经典极限的一个很好的候选者。实际上,在一个玻姆框架中,经典极限的问题就简化为展示在特定的经典性假设下,经典轨迹如何从玻姆轨迹中产生。在本文中,我们将专注于一个技术问题,从有界区域的Bohmian系统的动力学,我们建议,一个可能的解决方案是由环境退相干的行动。然而,我们将表明,为了实现退相干在一个玻姆框架,需要一个更强的条件(不相交的支持),而不是通常的(正交的状态)。

英文摘要:

Bohmian mechanics is a realistic interpretation of quantum theory. It shares the same ontology of classical mechanics: particles following continuous trajectories in space through time. For this ontological continuity, it seems to be a good candidate for recovering the classical limit of quantum theory. Indeed, in a Bohmian framework, the issue of the classical limit reduces to showing how classical trajectories can emerge from Bohmian ones, under specific classicality assumptions. In this paper, we shall focus on a technical problem that arises from the dynamics of a Bohmian system in bounded regions; and we suggest that a possible solution is supplied by the action of environmental decoherence. However, we shall show that, in order to implement decoherence in a Bohmian framework, a stronger condition is required (disjointness of supports) rather than the usual one (orthogonality of states).
