I am a condensed matter theorist. My research involves understanding the physics of strongly interacting quantum matter, with topics ranging from strongly-correlated electronic systems, quantum magnetism, topological phases of matter, non-Fermi liquids, unconventional superconductivity, many-particle entanglement, low-dimensional systems and quantum transport. One of my primary goals is to understand the fascinating and complex phenomenology displayed by many materials studied in the laboratory. I approach the problem by studying paradigmatic model Hamiltonians that are known to capture effectively the physics at the heart of many well-known quantum materials. An excellent example involves studying the two-dimensional Hubbard model on the square lattice to understand the enduring puzzle of high-temperature superconductivity displayed by the Cuprate family of materials. Such problems are hard as inter-particle interactions are of the same order as the kinetic energies, often causing perturbative approaches to fail. For dealing with such problems, I have developed a non-perturbative framework based on the renormalisation group. This is yielded a host of fresh insights and results on several challenging problems.
