I am a quantum condensed matter theorist investigating the interplay between topology, geometry and interaction effects in quantum materials. On conceptual grounds, I am interested in characterizing universal features of electronic states by studying novel topological/geometrical invariants and relating them to the quantum information content of quantum many-body systems. On practical grounds, I enjoy working with experimentalists to propose flexible platforms and accessible measurements to detect topological quantum matters.
My recent works focus on the topological aspects of metals and geometrical aspects of insulators. For metals, I have discovered relations between Fermi sea topology and multipartite quantum entanglement, and proposed quantized nonlocal transport experiments to extract the Fermi sea Euler characteristics. For insulators, I have been exploring new physical observable to probe the quantum metric of Bloch bands, such as via the corner charge fluctuation, which also provides a deep link between quantum geometry and quantum entanglement in insulating matters.
