Existence of Dirac resonances in the semi-classical limit
J. Kungsman, M. Melgaard
We study the existence of quantum resonances of the three-dimensional semiclassical Dirac operator perturbed by smooth, bounded and real-valued scalar potentials decaying like…

Complex absorbing potential method for the perturbed Dirac operator
J. Kungsman, M. Melgaard
The Complex Absorbing Potential (CAP) method is widely used to compute resonances in Quantum Chemistry, both for nonrelativistic and relativistic Hamiltonians. In the semiclassical…
