One of the overarching themes of our research is the investigations and applications of quantum coherent matter. In superconductors, superfluids, and Bose-Einstein condensates, a large fraction of constituent particles can occupy the same quantum ground state and behave in many ways as a single entity. We are interested in not only studying fascinating properties of such state of matter but also applying them as a set of tools to elucidate some subtleties of the quantum world. With disregard for presumed boundaries between applied physics, material science, and engineering, we also develop metamaterials and devices whose novel properties do not naturally exist in nature. Our current interests include superfluid and superconducting Josephson phenomena, nano/micro/meta-materials & devices, inertial sensing technologies, matter wave interferometry, and force/displacement sensing limits.
