One theorem named for this man can be used to derive the Wannier functions by applying it to a single band, then summing over the u sub k. One construct named for him is used to model two-level quantum systems, usually qubits. In addition to his namesake sphere, another set of equations named for this man sets the derivative of each component of M t equal to a term proportional to the gyromagnetic ratio plus a term containing T1 and T2. The previous formula decomposes a wavefunction into an exponential term and a periodic term, and applies to particles in a periodic potential.

The previous formula decomposes a wavefunction into an exponential term and a periodic term, and applies to particles in a periodic potential. He also lends his name to the transition regions between magnetic domains, his namesake "walls." For 10 points, name this physicist, who with Purcell, developed NMR.
