Reconciliation of Topological Switching Model with Femtosecond Laser Experiments

This work reconciles the topological phase transition model (with characteristic ∼0.5 ps switching time)with recent femtosecond laser experiments. We demonstrate that the apparent discrepancy resolves through hierarchical time scales: while global topology transitions occur at picosecond timescales, local algebraic re- structuring happens at femtosecond/attosecond scales. Modified junction terms with frequency-dependent damping and Gaussian transition profiles enable quantitative agreement with experimental data from topo-logical insulators and graphene. The model predicts resonant switching at 6.3 THz and quantum noisesignatures detectable with attosecond spectroscopy.
