Abstract:
Strongly correlated materials host a rich spectrum of non-equilibrium phenomena dominated by the on-site Coulomb repulsion. In charge-transfer insulators, this repulsion - denoted as the Hubbard -is theoretically predicted to undergo dynamic, sub-femtosecond modulations under intense laser fields, yet direct experimental observation of transient correlation dynamics has remained elusive. In this talk, we introduce two-color High-Harmonic Generation (HHG) spectroscopy to address this challenge. By leveraging phase-dependent driving fields to probe sub-cycle carrier trajectories, we isolate and track the ultrafast evolution of electron correlations in real time, providing a direct experimental benchmark for strong-field theory in correlated solids.
