Dr. Johnson earned his Ph.D. developing wavefunction models for strongly-correlated systems with Prof. Paul W. Ayers (McMaster University, Chemistry), as well as Prof. Dimitri Van Neck and Prof. Patrick Bultinck (Ghent University, Physics).
Project Description
The mechanisms of many novel materials and electronic devices are poorly understood in terms of the traditional orbital picture of quantum chemistry. Collective behavior can emerge as the inter-electronic repulsion becomes dominant. In this regime, many electronic configurations become important and hence traditional methods built upon individual configurations fail. We are therefore employing the solutions for models displaying collective behavior as a starting point to describe strongly-correlated electrons. A broad array of different wavefunction forms is being developed to describe the collective phenomena of interest.
