Research overview:

Our primary research interest lies in the behavior of electrons in novel low-dimensional materials with strong electron correlations. In these materials, the intricate interplay of the charge, spin, orbital and lattice degrees of freedom gives rise to a vast variety of intriguing phenomena that cannot be explained by conventional condensed matter theory. The outstanding examples of such materials include the cuprates high-temperature superconductors; colossal magnetoresistive manganites; thermoelectric sodium cobaltates; C60 fullerides, carbon nanotubes and graphene; organic metals/magnets/ superconductors; geometrically frustrated magnets and spin liquids; etc.

In our research we will develop a number of different experimental techniques, such as low temperature high field electro-thermal transport measurements; high-resolution magnetic and thermodynamic measurements; low temperature ultrahigh vacuum scanning tunneling microscopy and spectroscopy (STM/STS); etc. These different probes provide complimentary information regarding the exotic behavior of electrons in strongly correlated quantum materials.

Our secondary research interest is to synthesize and characterize emergent materials with novel superconducting, magnetic, magneto-resistive, and thermoelectric properties. These materials have great potentials in energy, environment, and information related technological applications.
