Abstract

Tailored light excitations provide a powerful means of initiating novel transformations and manipulating the properties of quantum materials on-demand. This work explores advancements in ultrafast single-shot optical and THz spectroscopy and its applications in the study of nonlinear material dynamics. First, we demonstrate the development of a new single-shot THz spectrometer capable of collecting multidimensional THz spectra two orders of magnitude faster than conventional delay line techniques. Next, we apply single-shot spectroscopy to capture the real-time formation of a metastable hidden metallic state in 1T-TaS2.
