磁场诱导的原子二体现象

Magnetic Field Induced Two-Body Phenomena in Atoms

Peter Schmelcher, Lorenz S. Cederbaum

摘要:

我们报告了一些最近发现的现象,这些现象是由于集体(CM)和内部运动的原子在磁场中运动的相互作用而产生的。对于中性原子,讨论了所谓的巨偶极态的性质,并概述了它们的实验制备。对于在磁场中运动的离子,研究了集体运动和电子运动之间的能量流。对于低CM速度,这导致从局部化到离域的交叉,相对于CM和内部运动在量子数空间中的混合的扩展。大CM速度诱导的经典以及量子离子的自电离过程。多电子原子以及分子的未来前景绘制。

英文摘要:

We report on a number of recently discovered phenomena which arise due to the interaction of the collective (CM) and internal motion of atoms moving in magnetic fields. For neutral atoms the properties of the so-called giant dipole states are discussed and their experimental preparation is outlined. For ions moving in magnetic fields the energy flow between the collective and electronic motions is studied. For low CM velocities this results in a crossover from localization to delocalization with respect to the spreading of the mixing of the CM and internal motion in quantum number space. Large CM velocities induce for both the classical as well as quantum ion the self-ionization process. Future perspectives for both multi-electron atoms as well as molecules are drawn.
