Schroedinger方程时间演化过程中的退相干

Decoherence during time evolution by Schroedinger equation

Shunichi Muto

摘要:

通过一个思想实验来阐明退相干的概念。讨论了单个氢原子的基态和它的激发态经过大量时间后的叠加态,指出态的退相干,更准确地说是相干性的丧失,实际上是干涉能力的丧失。态叠加的损失只是表面的,甚至是表面的。这个例子中的应用在其关系到多世界的解释观察的量子态,在通常情况下的退相干,和弱崩溃的波包进行了讨论。

英文摘要:

A thought experiment is discussed to clarify the concept of decoherence. Superposition of states consisting of ground state of a single hydrogen atom and its excited state after a huge amount of time is discussed to show that the decoherence of the state, more precisely the loss of coherence, is literally the loss of ability of interference. The loss of superposition of states is just apparent or even superfacial. Applications of this example in its relation to many-world interpretation of observation of a quantum state, decoherence in usual cases, and weak collapse of wavepackets are discussed.
