Electron wave functions on T2 in a static magnetic field of arbitrary direction

A basis set expansion is performed to find the eigenvalues and wave functions for an electron on a toroidal surface T2 subject to a constant magnetic field in an arbitrary direction. The evolution of several low-lying states as a function of field strength and field orientation is reported, and a procedure to extend the results to include two-body Coulomb matrix elements on T2 is presented.
