磁波导中的里德伯原子

Rydberg Atoms in a Magnetic Guide

Igor Lesanovsky, Joerg Schmiedmayer, Peter Schmelcher

摘要:

我们研究磁波导中的电子激发原子。事实证明,描述这个系统的哈密顿量拥有丰富的酉对称和反酉对称,构成了一个不寻常的广泛的对称群。结果之一是任何能级的双重简并。在较宽的场梯度范围内研究了其光谱特性,并分析了自旋极化的空间分布。给出了相应的电磁跃迁的波长、振子强度和选择规则。由于一个额外的均匀偏置场构成的Ioffe-Pritchard陷阱的影响进行了探讨。

英文摘要:

We investigate electronically excited atoms in a magnetic guide. It turns out that the Hamiltonian describing this system possesses a wealth of both unitary as well as antiunitary symmetries that constitute an uncommon extensive symmetry group. One consequence is the two-fold degeneracy of any energy level. The spectral properties are investigated for a wide range of field gradients and the spatial distributions of the spin polarization are analyzed. Wave lengths, oscillator strengths and selection rules are provided for the corresponding electromagnetic transitions. The effects due to an additional homogeneous bias field constituting a Ioffe-Pritchard trap are explored equally.
