We fabricate and characterize quantum materials with atomic thicknesses at femtosecond time scales. Utilizing the first-of-its-kind Microscopy And Spectroscopy for Transient Electronic-matter Research (MASTER) platform, we employ molecular beam epitaxy to engineer quantum materials layer-by-layer, and characterize the electronic structures of these materials using equilibrium and non-equilibrium photoemission spectroscopy. The holistic probing of quantum materials in the domains of energy, momentum, space, and time allows us to gain deep understanding of macroscopic quantum phenomena, and connect the material properties to applications in spintronics, topotronics, and quantum information sciences. We are particularly interested in quantum phenomena emerging at material interfaces, such as interfacial superconductivity and various topological orders. We are also developing new instrumentation which will allow us to print reconfigurable quantum circuits at sub-micron scales.
