双原子分子的磁光俘获

Magneto-optical trapping of diatomic molecules

Matthew T. Hummon, Mark Yeo, Benjamin K. Stuhl, Alejandra L. Collopy, Yong Xia, Jun Ye

摘要:

磁光阱的发展为原子和量子物理学领域带来了革命性的变化,它提供了一种快速产生超冷原子的简单方法。一种类似的技术,用于产生一组不同的致密、超冷的双原子分子物种,同样也将改变强相互作用量子系统、精密测量和物理化学的研究。我们演示了极性分子氧化钇(II)(YO)的一维和二维横向激光冷却和磁光捕获。使用准循环光学跃迁,我们观察到横向多普勒冷却的YO分子束的温度为5 mK,有限的相互作用时间。随着振荡磁四极场的加入,我们证明了横向磁光阱,并实现2 mK的温度。

英文摘要:

The development of the magneto-optical trap revolutionized the fields of atomic and quantum physics by providing a simple method for the rapid production of ultracold, trapped atoms. A similar technique for producing a diverse set of dense, ultracold diatomic molecular species will likewise transform the study of strongly interacting quantum systems, precision measurement, and physical chemistry. We demonstrate one- and two-dimensional transverse laser cooling and magneto-optical trapping of the polar molecule yttrium (II) oxide (YO). Using a quasicycling optical transition we observe transverse Doppler cooling of a YO molecular beam to a temperature of 5 mK, limited by interaction time. With the addition of an oscillating magnetic quadrupole field we demonstrate a transverse magneto-optical trap and achieve temperatures of 2 mK.
