... Section 2.5∗ :Quadratic Effects in the E × e-Problem We conclude our outline of the E×e - problem by pointing out that it contains far more points of degeneracy than just the origin, ρ = 0, and is thus of considerably higher complexity than suggested by the foregoing discussion. Expanding the potenti ...

In the absence of a magnetic field, the magnetic moments of atoms in a solid point in random directions (inset); as a magnetic field is applied, the magnetic vectors tend to align with the field. But the alignment is greater than predicted by classical ...
