Welcome to the Liu Group! We create, manipulate, visualize, and understand novel quantum states of matter. Experimentally, we implement scanning tunneling microscopy, scanned Josephson tunneling microscopy, and single atom/molecule manipulation at cryogenic temperatures. Read more about our research
