量子力学中态的时间演化

The Time-Evolution of States in Quantum Mechanics

Jürg Fröhlich, Alessandro Pizzo

摘要:

有人认为,薛定谔方程不产生一个正确的描述孤立(开放)系统的状态的量子力学时间演化的事件。在所谓的量子力学的ETH方法中,用一个精确的普遍定律来代替薛定谔方程。这一定律消除了臭名昭著的“测量问题”。“我们的一般结果是通过分析简单的模型来说明的,该模型描述了一个非常重的原子与量子化辐射场耦合,在光速趋于无穷大的极限下。对这些模型的讨论是本文的主要内容。

英文摘要:

It is argued that the Schrödinger equation does not yield a correct description of the quantum-mechanical time evolution of states of isolated (open) systems featuring events. A precise general law for the time evolution of states replacing the Schrödinger equation is formulated within the so-called ETH-Approach to Quantum Mechanics. This law eliminates the infamous "measurement problem." Our general results are illustrated by an analysis of simple models describing a very heavy atom coupled to the quantized radiation field in a limit where the speed of light tends to infinity. The discussion of these models is the main subject of our paper.
