Spurious Modes in Dirac Calculations and How to Avoid Them    [PDF]

Mathieu Lewin, Eric Séré
In this paper we consider the problem of the occurrence of spurious modes when computing the eigenvalues of Dirac operators, with the motivation to describe relativistic electrons in an atom or a molecule. We present recent mathematical results which we illustrate by simple numerical experiments. We also discuss open problems.
