Figure A5. The axial wavefunctions of hydrogen in an intense magnetic field (analytic calculation)<br />
<strong>for</strong> B = 4.7 · 10 12 Gauss. The first four even states <strong>with</strong> axial excitations, |000〉 (ground<br />
state), |002〉, |004〉, and |006〉 (left panel), and odd states |001〉 and |003〉 (right panel) are<br />
depicted; n = 1/ √ 15.58, ζ = 2z/n corresponds to x in <strong>the</strong> used notation; z in a.u., 1 a.u. =<br />
0.53 · 10 −8 cm (reproduction of Figure 3 by Heyl and Hernquist [14]).<br />
Heyl and Hernquist calculated <strong>the</strong> first-order perturbative corrections to <strong>the</strong><br />
above energies and obtained <strong>the</strong> values, which are in a good agreement <strong>with</strong><br />
<strong>the</strong> results by Ruder et al. [9] and Lai [12].<br />
The associated probability density of <strong>the</strong> above excited states is evidently of a<br />
cylindrical (axial) symmetry and can be described as two Landau orbits of radius<br />
R 0 in different (r, ϕ) planes, one at <strong>the</strong> level z = −L z , and <strong>the</strong> o<strong>the</strong>r at <strong>the</strong><br />
level z = +L z , <strong>with</strong> <strong>the</strong> nucleus at z = 0, as schematically depicted in Fig. A6.<br />
Presence of two Landau orbits occurs in accord to <strong>the</strong> excited wave functions,<br />
which is symmetrical <strong>with</strong> respect to <strong>the</strong> inversion, z → −z, and <strong>the</strong> largest peaks<br />
of which are away from <strong>the</strong> center x = 0. The electron moves simultaneously on<br />
<strong>the</strong>se two Landau orbits.<br />
A review of approximate, variational, and numerical solutions can be found<br />
in <strong>the</strong> paper by Lai [12]. The accuracy of numerical solutions is about 3%,<br />
<strong>for</strong> <strong>the</strong> external magnetic field in <strong>the</strong> range from 10 11 to 10 15 Gauss. Particularly,<br />
due to <strong>the</strong> variational results [12], <strong>the</strong> z-size of <strong>the</strong> hydrogen atom in <strong>the</strong><br />
ground state is well approximated by <strong>the</strong> <strong>for</strong>mula L z ≃ [ln(B/B 0 )] −1 a.u.; <strong>the</strong>
