大分子二聚体:超长程Rydberg分子

Macrodimers: ultralong range Rydberg molecules

Christophe Boisseau, Ionel Simbotin, Robin Cote

摘要:

我们研究了两个里德伯原子之间的长程相互作用,并预言了平衡距离为数千玻尔半径的超长里德伯二聚体的存在。计算了两个铷原子在同一激发态$np$下的色散系数$C_{5}$、$C_{6}$和$C_{8}$,发现它们分别具有类似于$n^{8}$、$n^{11}$和$n^{15}$的标度.我们表明,对于某些分子的对称性,这些系数导致长程势阱,可以支持分子结合水平。这样的大二聚体将对它们的环境非常敏感,并且可以探测弱相互作用。我们建议实验来检测这些大二聚体。

英文摘要:

We study long range interactions between two Rydberg atoms and predict the existence of ultralong range Rydberg dimers with equilibrium distances of many thousand Bohr radii. We calculate the dispersion coefficients $C_{5}$, $C_{6}$ and $C_{8}$ for two rubidium atoms in the same excited level $np$, and find that they scale like $n^{8}$, $n^{11}$ and $n^{15}$, respectively. We show that for certain molecular symmetries, these coefficients lead to long range potential wells that can support molecular bound levels. Such macrodimers would be very sensitive to their environment, and could probe weak interactions. We suggest experiments to detect these macrodimers.
