HARMONIC FLOQUET DYNAMICS, SUBCYCLE ATTOSECOND GATING, AND OPTICAL METRIC INDUCTION

Recent experimental breakthroughs in ultrafast condensed matter physics [Lesko et al., Nature Physics 22, 1607–1614 (October 2026)] have demonstrated the all-optical generation and dynamical control of electrons in a Floquet topological insulator (FTI).By driving monolayer graphene with circularly polarized femtosecond pulses at ω = 0.8 eV (1, 550 nm) and probing with a phase-locked second harmonic (2ω = 1.6 eV, 775 nm), Lesko et al. observed photocurrent circular dichroism, an all-optical anomalous Hall effect, and valley-polarized currents governed by subcycle attosecond micromotion.In this treatise, we establish a mathematically closed, first-principles synthesis connecting the experimental findings of Lesko et al. to the Deterministic Spectral Manifold (DSM-861) optical metric engineering framework. We show that light-dressed Floquetengineering in solid-state honeycomb lattices serves as an exact physical analogue simulator for non-equilibrium metric and gauge induction in the Heegner-vorton quantum vacuum.We prove f
