Current professional interests:
Theoretical and numerical nonlinear optics/electrodynamics, including low-dimensional structures (surfaces, interfaces, quantum wires and -dots).
Active projects:
Theoretical studies of nonlinear optical properties of magnetic thin films based on ab initio (from electronic structure) calculations of the material properties and an electric-dipole description of the optical interaction. In collaboration with Dr. W. H�bner, University of Kaiserslautern, Germany.
Theoretical models for relativistic nonlocal nonlinear optics. In collaboration with Professor O. Keller, Institute of Physics, Aalborg University, Denmark.
Combination of these two projects is planned and being worked on.
Ab-inito optical studies of CO₂ and Ce.
Sleeping projects:
(i) phase conjugation in mesoscopic interaction volumes - with particular attention drawn to phase conjugation by degenerate four-wave mixing in metallic quantum wells, (ii) spatial confinement of light, (iii) the influence of spatial dispersion in nonlinear optics.
Memberships of professional societies:
Danish Optical Society 1988-present.
American Physical Society 1995-present (lifetime member since 2003).
