隧道的多体相干破坏

Many-Body Coherent Destruction of Tunneling

Jiangbin Gong, Luis Morales-Molina, Peter Hanggi

摘要:

通过考虑多玻色子系统自相互作用强度的单色快速调制,建立了一条隧道相干破坏的新途径。调制可以被调谐,使得仅允许任意的、先验规定数量的粒子隧穿。相关的隧穿动力学对玻色子数量的奇数或偶数性质很敏感。

英文摘要:

A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulation can be tuned such that only an arbitrarily, a priori prescribed number of particles are allowed to tunnel. The associated tunneling dynamics is sensitive to the odd or even nature of the number of bosons.
