光晶格中的自旋-自旋相互作用和自旋压缩

Spin-spin interaction and spin-squeezing in an optical lattice

Anders Sorensen, Klaus Molmer

摘要:

我们表明,通过取代两个光晶格相对于彼此,我们可能会产生类似的相互作用,描述在凝聚态物理的铁磁性。我们还表明,特别简单的相互作用的选择导致自旋压缩,这可能是用来提高原子钟的灵敏度。自旋压缩产生的部分,随机,填充晶格,我们的建议可以实现与当前的技术。

英文摘要:

We show that by displacing two optical lattices with respect to each other, we may produce interactions similar to the ones describing ferro-magnetism in condensed matter physics. We also show that particularly simple choices of the interaction lead to spin-squeezing, which may be used to improve the sensitivity of atomic clocks. Spin-squeezing is generated even with partially, and randomly, filled lattices, and our proposal may be implemented with current technology.
