Computational Condensed Matter Physics (CCMP) Group
University of Arkansas

We carry out research in the field of computational condensed matter physics. Our current interests mainly lie in developing and/or using direct first-principles methods, first-principles-based techniques and semi-empirical approaches to:

– predict topological defects and related phenomena in ferroelectrics (including relaxors) and  multiferroics.
– reveal Kitaev-type spin liquids, as well as magnetic skyrmions and frustration, in novel 2D systems.
– investigate non-equilibrium effects, mostly for neuromorphic computing, in various compounds.
– optimize subtle cross-coupling properties, including electro-optic, electrocaloric, elasto-optic, piezoelectric and (static and dynamical) magnetoelectric effects.
– understand at a microscopic level complex light-matter interactions and photovoltaic materials.
– design antiferroelectrics with high energy densities and efficiencies.
– demonstrate that some structural defects can enhance physical properties or even create novel phenomena.

Close collaboration with experimental teams are often conducted, and analytical derivations are sometimes accomplished, to better tackle these topics. Other subjects are pursued from time to time.

For students, researchers and scientific development, we are founding members of the Smart Ferroic Materials Center, which promotes research on functional materials through exchanges with international institutions such as CentraleSupélec in France.
