= GaAs four-band model
{c}

A zone-centre effective-mass description retaining the s-like <conduction band>, heavy-hole and light-hole branches of the p-like $j=3/2$ valence manifold, and the spin-orbit-split $j=1/2$ valence branch. Each named branch includes <spin> multiplicity; four bands does not mean four individual quantum states.
