Driven Quantum Systems Reveal Hidden Topological Changes Via Wave Packet Motion
A team led by Xin Shen introduced an extended‑Hilbert‑space perturbative framework that amplifies centre‑of‑mass (CoM) oscillations of wave packets in periodically driven (Floquet) quantum systems by roughly 1,883 times. The method captures multi‑frequency motion that mirrors the underlying Floquet band structure, allowing topological phase transitions to be identified through low‑frequency shifts and phase changes. By overcoming the limitations of the conventional Floquet‑Magnus expansion, the approach remains accurate even when driving frequencies exceed material energy gaps. The findings suggest a practical, experimentally accessible route to probe topological invariants in strongly driven materials.
