Vincent Sokalski
Our research is focused on the exploration of novel magnetic & spintronic materials for memory, logic, and HDD storage applications. We concentrate on the development of thin films & nanoscale devices that will enable improved energy efficiency, non-volatility, and scalability to ever-decreasing dimensions. Current research efforts include crystallographic & microstructural characterization of perpendicular magnetic recording media, materials for spin hall effect devices, spin transfer torque magneto-resistive random access memory (STT-MRAM), and magnetic interactions in soft nanogranular composite thin films.

Our group designs hypothetical materials to help address energy and environmental challenges. We are interested in creating sophisticated nanostructures; potentially as complex (and useful) as molecular machines found in Nature. Our strategy is to computationally design and study new materials and then work work with our experimental collaborators to synthesize those materials in the lab. We are active software developers, and we build new computational tools to address problems nobody has tackled before.
My research interests centers on the strong and weak interactions of the Standard Model. In particular, I use effective field theory techniques to study heavy quarks as a probe of these interactions, and to try to uncover physics beyond the Standard Model. I am also interested in gravitational waves, the physics of extra dimensions, supersymmetry, in matter at extreme densities, and on physics relevant to the Large Hadron Collider.
