原子离子在磁场中的介观运动

Mesoscopic motion of atomic ions in magnetic fields

David M. Leitner, Peter Schmelcher

摘要:

我们引入了一个半经典模型来描述高激发态原子离子在磁场中的运动,它使我们能够用电子激发和磁场来描述质心朗道轨道的混合。研究了离子中量子能流的程度,并检测到随着质量质心能量的增加从局域化到离域的交叉。事实证明,我们在磁场中移动离子的模型与无序有限尺寸导线中的传输模型密切相关。

英文摘要:

We introduce a semiclassical model for moving highly excited atomic ions in a magnetic field which allows us to describe the mixing of the Landau orbitals of the center of mass in terms of the electronic excitation and magnetic field. The extent of quantum energy flow in the ion is investigated and a crossover from localization to delocalization with increasing center of mass energy is detected. It turns out that our model of the moving ion in a magnetic field is closely connected to models for transport in disordered finite-size wires.
