Directions

We are broadly interested in uncovering and understanding novel quantum phenomena in correlated electron systems. Current research topics include: unconventional superconductivity in transition-metal oxides, novel electronic phases in doped Mott insulators, and emergent metallicity in correlated narrow-gap insulators.

Current projects

High-Tc cuprates

The only known materials family which superconducts at temperatures above 90 K at ambient pressure.

Perovskite iridates

An attractive system to explore novel quantum phenomena driven by the interplay between Coulomb and spin-orbit interactions.

Layered nickelates

A close analogue to the high-Tc cuprates with a ‘cleaner’ phase diagram and a more accessible normal electronic ground state.

Narrow-gap insulators

Paradoxical materials displaying metallic signatures within a bulk insulating state, suggestive of a new quantum state of matter.
