Vacuum ultraviolet (VUV) lasers have exhibited great potential as the light source for various spectroscopies, which, if they can be focused into a smaller beam spot, will not only allow investigation of mesoscopic materials but also find applications in manufacture of nano-objects with excellent precision. Towards this goal, scientists in China invented a 177 nm VUV laser system that can achieve a record-small (<1 渭m) focal spot at a long focal length (~45 mm). This system can be re-equipped for usage in low-cost ARPES and might benefit quantum materials, condensed matter physics and nanophotonics.

My research interest lies in experimental condensed matter physics, including understanding the behavior of electrons in unconventional materials such as topological quantum matter and strongly correlated systems. I'm also interested in developing advanced instrumentation that will drive the exploration of critical information on condensed matter systems with new degrees of freedom.
