  • G-Convergence of Dirac Operators 
    Almanasreh, Hasan; Svanstedt, Nils (Journal of Function Spaces, 2012-03-16)
    We consider the linear Dirac operator with a (-1)-homogeneous locally periodic potential that varies with respect to a small parameter. Using the notation of G-convergence of positive definite self-adjoint operators in ...
  • Stabilized Finite Element Method For The Radial Dirac Equation 
    Almanasreh, Hasan; Salomonson, Sten; Svanstedt, Nils (Journal of Computational Physics, 2013-03-01)
    A challenging difficulty in solving the radial Dirac eigenvalue problem numerically is the presence of spurious (unphysical) eigenvalues, among the genuine ones, that are neither related to mathematical interpretations nor ...
