Research Description

Prof. Nevidomskyy is a theoretical physicist working in the field of condensed matter. His work focuses on materials in which electrons interact strongly with each other, resulting in a very different behaviour from ordinary metals such as aluminium and copper. The examples include, among others, the recently discovered iron-based superconductors, frustrated quantum magnets, and heavy fermion metals. The latter class of materials is particularly intriguing because the electrically charged particles of which they consist, fermions, are unlike ordinary electrons. The interactions between the fermions are so strong that these particles acquire a very heavy mass, often several hundred times greater than that of a bare electron. As a result of this heaviness, many material properties are profoundly affected. In particular, the electric current and thermal heat flow differently through these
materials at low temperatures. By applying pressure or chemical doping, these materials can be tuned to the so-called quantum phase transition at absolute zero temperature. Exotic quantum phases, such as unconventional superconductivity, often form near this critical point, making this phenomenon especially intriguing.

To study the properties of these correlated electron materials, Nevidomskyy employs a combination of the realistic electron band theory, which takes into account the details of chemical and structural composition, and the state-of-the-art analytical and numerical techniques to solve the effective many-body problem. By collaborating closely with experimental colleagues at the Center, Nevidomskyy has successfully applied this combined approach to shed light on the properties of heavy fermion materials and iron-based superconductors. 

biography

Born in Ukraine, Nevidomskyy obtained his B.Sc. (summa cum laude) and Masters degree from Ivan Franko National University of Lviv, before completing his Ph.D. in theoretical physics at the University of Cambridge, UK in 2005. He continued research in the field of strongly correlated materials at Université de Sherbrooke in Canada and at Rutgers University of New Jersey, before joining Rice University in 2010. Nevidomskyy is a recipient of the Cottrell Scholar Award from Research Corporation for Science Advancement, and the CAREER young investigator award from the National Science Foundation.
