I am a Scientist in Raytheon BBN Technology and an Associate of Physics Department at Harvard University. My research focuses on studying the hydrodynamics in the Dirac and Weyl semimetals. Specifically, I am interested in (1) how this novel paradigm of the strongly interacting many-body system modifies our conventional understandings of the electrical and thermal transport properties in condensed matter physics, and (2) its deep connection to the fundamental physics such as the chiral anomaly and anti-de Sitter/conformal field theory (AdS/CFT) bound. A prime example along this direction is my experiment demonstrating the breakdown of the Wiedemann-Franz law in graphene as the hydrodynamic Dirac fluid forms near the Dirac point. Understanding the Dirac and Weyl fermions can lead to new applications, such as the (3) graphene-based Josephson junction single photon detector for quantum computations and radioastronomy and (4) novel two-dimensional materials-based superconducting quantum devices. It is my privilege to collaborate with many outstanding scientists. The interaction with them has inspired a lot of my research and makes my professional life colorful in many ways. I am grateful for the funding supports from ARO, NSA, and Raytheon BBN Technologies.
