For 10 points, name this German physicist who names an approximation with Robert Oppenheimer.
This scientist is the alphabetically first namesake of modified field equations which add a finite electron radius to remove the divergence of the electron's self energy. Plane motions and group motions generated by a Killing field are two of the three degrees of freedom for bodies possessing this scientist's namesake rigidity according to the Herglotz-Noether theorem. Along with naming a model with Leopold (*)Infeld, he names boundary conditions which can be used to prove Bloch's theorem. He co-names those boundary conditions that restrict a wavefunction to be periodic on Bravais lattices with von Karman. With Jordan and Heisenberg, he formulated the matrix mechanics representation of quantum mechanics. He is the alphabetically first namesake of an assumption that uses the slow relative motions of nucleons to separate their wavefunction from the electrons'.
