Reflection of matter waves by a moving wall
arXiv:quant-ph/0203054
Abstract
Reflection of a normal incident matter wave by a perfectly reflecting wall moving with a constant velocity is investigated. A surprising phenomenon is found-that if the the wall moves faster than the phase velocity of the incident wave, both the reflected and incident waves propagate in the same direction. This counter-intuitive result is an example which shows that common sense is not always credible when one deals with quantum problems.
