Ph.D., 1997, Pennsylvania
Maxine S. and Jesse W. Beams Professor of Physics
Experimental Condensed Matter Physics
Professor Louca studies phase transitions in condensed matter systems. Louca is interested in understanding how the underlying interactions involving the spin, charge and lattice degrees of freedom lead to emergent behaviors and properties such as polaron formation, Jahn-Teller type distortions, spin and charge density waves, superconductivity and quantum spin liquid states. The most recent systems of interest include topological insulators and semimetals, spintronic antiferromagnets of the I-Mn-V class, transition metal dichalcogenides, disorder superconductors, layered semiconductors, charge density wave dichalcogenides etc. These systems have underlying macroscopic functionalities that can potentially lead to industrial applications. The bulk of this research is performed at national and international neutron and X-ray facilities. The Louca group is also involved inmaterials synthesis and characterization of bulk properties, performed at the University of Virginia.
