力的量子干涉

Quantum Interference of Force

Raul Corrêa, Marina F. B. Cenni, Pablo L. Saldanha

摘要:

我们表明,一个量子粒子受到一个积极的力在一个路径的马赫-曾德尔干涉仪和零力在其他路径可能会收到一个负的平均动量转移时,它离开干涉仪的特定出口。在这种情况下,由于量子干涉,粒子系综可能会在施加的力的相反方向上接收平均动量,这是一种没有经典模拟的行为。我们讨论了一些实验方案,可以验证与当前的技术效果,与电子或中子在马赫-曾德尔干涉仪在自由空间和原子从玻色-爱因斯坦凝聚体。

英文摘要:

We show that a quantum particle subjected to a positive force in one path of a Mach-Zehnder interferometer and a null force in the other path may receive a negative average momentum transfer when it leaves the interferometer by a particular exit. In this scenario, an ensemble of particles may receive an average momentum in the opposite direction of the applied force due to quantum interference, a behavior with no classical analogue. We discuss some experimental schemes that could verify the effect with current technology, with electrons or neutrons in Mach-Zehnder interferometers in free space and with atoms from a Bose-Einstein condensate.
