原子的无序冷却和囚禁

Atom cooling and trapping by disorder

Peter Horak, Jean-Yves Courtois, Gilbert Grynberg

摘要:

我们证明了三维冷却的中性原子的可能性,通过照射它们与两个相互正交的线偏振的反向传播的激光束,其中一个激光是一个散斑场,即一个高度无序的,但稳定的相干光场。这种结构通过西西弗斯冷却机制引起横向平面中的原子冷却,该机制类似于由几个平面激光波形成的标准二维光晶格中已知的机制。然而,显着的差异发生在空间扩散系数,以及在本地属性的被困原子。

英文摘要:

We demonstrate the possibility of three-dimensional cooling of neutral atoms by illuminating them with two counterpropagating laser beams of mutually orthogonal linear polarization, where one of the lasers is a speckle field, i.e. a highly disordered but stationary coherent light field. This configuration gives rise to atom cooling in the transverse plane via a Sisyphus cooling mechanism similar to the one known in standard two-dimensional optical lattices formed by several plane laser waves. However, striking differences occur in the spatial diffusion coefficients as well as in local properties of the trapped atoms.
