Algorithm-augmented ultrafast spectroscopy
Project Description
Ultrafast laser pulses have emerged as an advantageous tool to uncover complex interaction and unlock novel functionalities in quantum materials. This is largely made possible by the superb temporal resolution of modern femetosecond laers for triggering novel non-equilbirum phase transitions. Despite the success in capturing post-laser-escitation dynamics, it remains a challenge to unveal the radically faster rising dynamics from equilibrium to non-equilibrium state, which bears essential microscopic mechanism enabling the photo-induced phase transition pathway. The resolution to the challenge requires methodology for spectroscopic analysis with hyper resolution, that is, a temporal resolution beyond the “shutter” speed of the instrument. In this project, we explore the possibility to acquire such resolution by algorithm-augmented technique.
