Bz is the uniform magnetic field. The eigenstates at the initial and final times are labeled. Adiabatic state transfer can occur by initializing the system in either the \({E}_{-}^{+1/2}\) or \({E}_{-}^{-1/2}\) states. Here, the superscript is z-component of the spin angular momentum (Sz), and subscripts denote different eigenstates within a particular Sz subspace.
