Our research focuses on the characterization of physical properties and structures of materials through thermodynamic, transport, X-ray and neutron measurements, with an emphasis on the design, synthesis and crystal growth of new materials. Our interests span a wide spectrum of materials, from intermetallics to oxides, especially superconductors and strongly correlated electron systems showing unusual electronic and magnetic ground states that can be perturbed by chemical doping, applied pressure or magnetic field. We aim at synthesizing new materials with nontrivial properties, characterizing quantum phases, and examining the different energy scales in solids. The interplay of magnetism, superconductivity and structure will be of particular interest.

03/2019 Our collaborative work on the Weyl semimetal TaAs with the Burch group at Boston College is online on Nature Materials. This work discovered that TaAs has a colossal bulk photovoltaic effect, which generates current from light more than ten times larger than ever previously achieved. The findings may offer a new route to efficient generation of electricity from light, as well as for thermal or chemical sensing.
