    "summary": "A strong-drive theory treats pulse duration, amplitude and shape as design variables that can create interactions absent from the original qudit system.",
    "body_text": "Floquet protocols are often designed with instantaneous pulses even though laboratories use finite waveforms. The new framework incorporates those realizable pulses into the effective interaction. In three-level systems, one pulse turns a diagonal interaction into a spin-1 model dominated by nematic terms; other protocols produce enlarged SU(2)×U(1) and SU(3) symmetries. Numerical tests support the derived dynamics, but the paper presents theory and simulation rather than a completed quantum device.",
