Particle movement effects on bound state energies. Solid lines represent energies (without kinetic contribution from motion along the field) of magnetized atoms for a few states (ν, m) as a functionof the transverse pseudo-momentum, at β = 500 (B = 2.35 × 10¹² G). Results without finite-velocity effects are indicated by dotted lines. Approximations based on Eqs. (21), (28), and (31) are displayed as short-dashed, long-dashed [only for (0, 0), (1, 0) and (2, −1) states], and dot-dashed lines, respectively.
