Abstract

Recent developments in high-power ultrafast optical technology and emerging theoretical frameworks in strong-field quantum electrodynamics (SF-QED) are unveiling nuanced differentiations between the semi-classical and full quantum mechanical descriptions of physical systems. Here we present a computational investigation of a novel technique for attosecond optical sensing through time correlation transduction (TCT) by investigating high-harmonic generation (HHG) as a representative SF-QED process. TCT is an experimental method to capture photon-electron interactions at higher harmonic orders by temporarily correlating the emitted and driving photon fields. This approach enables resolving the dynamical behavior of optically-driven strong-field phenomena in quantum materials such as Two-dimensional Materials and Dirac Semimetals down to 10 attosecond temporal resolution to discover a full quantum explanation. Predicting and measuring the transition between perturbative and non-perturbative regimes with attosecond resolution can deepen the understanding of SF-QED such as HHG. As such, we find that TCT is a powerful method to pave the way toward the functional characterization of quantum matter.
