About Me

I work on condensed matter theory, with a focus on low-dimensional quantum physics. The main interest is to predict/explain novel quantum phenomena that arise from the interplay of symmetry, topology, and many-body interactions. I have been studying a variety of topics, including, single-particle as well as many-body physics in moiré superlattices, superconductivity, topological phases of matter, light-matter interactions, and quantum Hall effects. With my collaborators, I made a number of theoretical predictions that have far-reaching impacts on the field, as many of them have been experimentally realized/verified.

• Proposal of using semiconductor moiré bilayers as quantum simulators (PRL)

see Nature, Nature, and Nature for experimental realizations.

• Prediction of topological phases in semiconductor moiré bilayers (PRL)

see Nature for observation of quantum anomalous Hall effects in MoTe2/WSe2.

• Prediction of signatures of moiré excitons in optical spectrum (PRL, PRB)

see Nature, Nature, Nature, Nature, and Nature for observation of moiré excitons and polaritons.

• Prediction of phonon-induced giant T-linear resistivity in graphene moiré systems (PRB)

see PRL, Nature Physics, and arxiv for observation of T-linear resistivity in graphene moiré systems.

• Prediction of phonon-mediated unconventional pairings in graphene-based systems (PRL,PRB)

see PRL and PRL for applications of our theory to study SC in graphene-based systems.
