Background
To capture the time evolution of a fast process, we need an even faster probe that allows us to "freeze" the motion into a series of snapshots. Intense, ultrashort laser pulses provide such a probe, enabling scientists to not only observe but also control electron and nuclear dynamics on their natural timescales — ranging from attoseconds (10^{-18} seconds) to femtoseconds (10^{-15} seconds). Understanding and controlling these ultrafast electron dynamics is of fundamental and technological importance, as electron motion underpins processes such as current flow in materials and the initiation of chemical reactions.
Lun Yue's theoretical research is in strong-field and ultrafast physics, focusing on both condensed-phase and gas-phase systems. He aims to develop the theoretical frameworks and numerical tools necessary to predict, control and probe the nonperturbative phenomena arising from strong laser-matter interactions. His research interests span from high-frequency light generation in two-dimensional, bulk and topological materials to the study of correlation-induced fragmentation in molecules.
