光晶格中的介观量子相干性

Mesoscopic quantum coherence in an optical lattice

D. L. Haycock, P. M. Alsing, I. H. Deutsch, J. Grondalski, P. S. Jessen

摘要:

我们观察了原子旋量波包在远共振光晶格双势阱中的量子相干动力学。在适当的初始条件下,拉比系统在基态偶极子的左右局域态之间振荡,在某些时候,波包对应于这些介观可区分的量子态的相干叠加。原子/光学双阱势是研究介观量子相干性、量子控制和量子/经典跃迁的一个灵活而强大的系统。

英文摘要:

We observe the quantum coherent dynamics of atomic spinor wavepackets in the double well potentials of a far-off-resonance optical lattice. With appropriate initial conditions the system Rabi oscillates between the left and right localized states of the ground doublet, and at certain times the wavepacket corresponds to a coherent superposition of these mesoscopically distinguishable quantum states. The atom/optical double well potential is a flexible and powerful system for further study of mesoscopic quantum coherence, quantum control and the quantum/classical transition.
