世界时时间

Universal Time Tunneling

Guenter Nimtz

摘要:

一个隧穿波包穿越势垒需要多少时间?量子力学计算的结果是势垒内的时间为零。在90年代进行了类似的微波隧道实验。结果与量子力学计算结果一致。电子隧穿时间由于极短而难以测量,并且由于电子的电荷引起的寄生效应可能占主导地位。然而,最近已经测量了原子电离隧穿时间。光子,声子和电子隧穿时间的实验数据现在是可用的,并将提出。看来隧穿时间是一个独立于所讨论的场的普适性质。

英文摘要:

How much time does a tunneling wave packet spent in traversing a barrier? Quantum mechanical calculations result in zero time inside a barrier . In the nineties analogous tunneling experiments with microwaves were carried out. The results agreed with quantum mechanical calculations. Electron tunneling time is hard to measure being extremely short and parasitic effects due to the electric charge of electrons may be dominant. However, quite recently the atomic ionization tunneling time has been measured. Experimental data of photonic, phononic, and electronic tunneling time is available now and will be presented. It appears that the tunneling time is a universal property independent of the field in question.
