隧道化过程中的想象时间

The Imaginary Time in the Tunneling Process

Zhong Chao Wu

摘要:

通过使用量子宇宙学中发展的技术,发现隧穿粒子在势垒区上花费的时间纯粹是虚的。{ \it虚}时间与状态的随机因果行为相关联,而{ \it实}时间与状态的确定性因果演化相关联。对于隧穿情况,非零虚时间与隧穿过程的传输速率有关,而传输速率与势垒的厚度有关。零真实时间的物理意义是粒子瞬间从屏障的一侧跳到另一侧,而不管厚度如何。这导致了一种错觉,即隧穿粒子实际上可以比光传播得更快。最近量子光学中关于隧穿时间的实验结果可以被认为是虚时间存在的第一个实验证实。相对性没有被侵犯。

英文摘要:

By using techniques developed in quantum cosmology, it is found that a tunneling particle spends purely imaginary time on a barrier region. The {\it imaginary} time is associated with the stochastic acausal behaviour of a state, while the {\it real} time is associated with the deterministic causal evolution of a state. For the tunneling case the nonzero imaginary time is associated with the transmission rate of the tunneling process, which is related to the thickness of the barrier. The physical meaning of the zero real time is that the particle instantly jumps from one side of the barrier to the other regardless of the thickness. This leads to the illusion that tunneling particles could actually travel faster than light. The results of recent experiments in quantum optics concerning tunneling time can be thought of as the first experimental confirmation of the existence of imaginary time. Relativity is not violated.
