我们回顾了最近的研究结果的类氢系统在磁场强度的洛伦兹力是可比的，或大于库仑结合力。这种情况是实现了典型的磁场强度的磁白色矮星和中子星的低洼状态，而里德堡州已经实验室的场强是足够的。我们讨论的波长光谱的氢原子在磁场中的任意强度，并描述以何种方式的光谱的“固定线”，出现在这个光谱，有可能检测到的最大磁场强度曾经发现的白色矮星星星的日期。对于里德伯态在强的实验室领域，我们进行了实验和理论光谱之间的定量比较，并证明了“量子随机性”的症状恢复磁化里德伯原子的光谱。特别指出量子问题中准可分性的破坏与经典问题中正则轨道的消失密切相关。我们的结论是，磁化里德堡原子借给自己作为理想的对象，在其中研究，理论和实验，量子随机性的表现。
We review recent results of investigations of hydrogen-like systems at magnetic field strengths where the Lorentz forces are comparable to, or larger than, the Coulomb binding forces. This situation is realized for low-lying states at field strengths typical of magnetic white dwarfs and neutron stars, while for Rydberg states already laboratory field strengths are sufficient. We discuss the wavelength spectrum of the hydrogen atom in magnetic fields of arbitrary strength, and describe in which way the spectroscopy of "stationary lines", which appear in this spectrum, has made possible the detection of the largest magnetic field strength ever found in a white dwarf star to date. For Rydberg states in strong laboratory fields we perform a quantitative comparison between experimental and theoretical spectra, and demonstrate that symptoms of "quantum stochasticity" are recovered in the spectra of magnetized Rydberg atoms. In particular we point out that the breakdown of quasi-separability in the quantal problem is closely related to the disappearance of regular orbits in the classical problem. We conclude that magnetized Rydberg atoms lend themselves as ideal objects in which to study, theoretically and experimentally, manifestations of quantum stochasticity.
