Dr. Haraldsen works on theoretical and computational condensed matter physics, where he utilizes various techniques that are centered around exact diagonalization, phenomenological, mean-field, and density functional methods and approaches. Overall, he is interested in investigating the complex states and competing interactions between charge, spin, and lattice degrees of freedom in magnetic and charge-order materials. Recently, Dr. Haraldsen has been working on understanding the interactions at complex oxide interfaces for multilayers as well as surface states and magnetoelectric transport in 2D and Dirac materials. The overall goal is to model and predict materials that have the potential to be utilized for applications within spintronic and multiferroic devices.
