Saddle-Point Variational Method for the Dirac Equation

Abstract
Variational solutions are found for the Dirac equation for various potentials. The stationary energy values correspond to saddle points in parameter space. This has the effect of limiting both negative- and positive-energy contributions. Comparison with exact numerical results shows good agreement for the energy and for other expectation values.
