Welcome to the Demkov materials physics group!

Our current research is focused on the physics of oxide heterostructres. We work on the quantum theory of real materials, and molecular beam epitaxy (MBE). Owing to the complexity of these problems, our research requires high performance computing, most of which is done at the Texas Advanced Computing Center (TACC), and the state of the art MBE Lab . We do both theoretical and experimental research. To the right is a list of our most recent papers (a full list is available under the publications tab).

We are always interested in recruiting new students who are interested in condensed matter physics, and hope you will consider our group for your studies.
