Research Interest
Experimental condensed matter physics using neutron and X-ray scattering. Focus on novel magnetic properties of strongly correlated electron systems, especially the systems that fail to develop static long range order despite strong interactions due to intrinsic effects. The systems of interest include geometrically frustrated magnets, magnetic molecules, doped antiferromagnets, heavy fermion systems, and superconductors. Exotic states, novel phase transitions, and interplay between spin, charge and orbital degrees of freedom in those systems are his focus.
