Works on quantum phenomena in strongly correlated materials including unconventional superconductors, emergent phenomena at oxide interfaces such as superconductivity and magnetism, combining orders at interfaces, i.e. superconductivity and ferroelectricity, superconductivity and magnetism, ferroelectricity and ferromagnetism, topological insulators and superconductors and quantum spin-liquids.
Research achievements include: Measuring the spin-orbit interaction in strontium titanate-based oxide interfaces and understanding its effect on superconductivity both for (100) and (111) directions.; understanding the role of electronic correlations in the band structure of interfaces and its effects on quantum oscillations and transport properties; designing and fabricating quantum wires without spin degeneracy from strontium titanate based oxide interfaces; understanding the evolution of the Fermi surface in doped topological insulators; understanding the role of oxygen, holes and electrons in electron-doped cuprate superconductors; finding exotic superconductivity and possible quantum spin liquid in various allotropes of tantalum disulfide.
Future directions include: Combining orders of ferroelectricity, superconductivity, and magnetism at oxide interfaces, interface enhanced superconductivity, quantum oscillations in candidate spin liquids and exotic superconductors.
