Summary

A strong-drive theory treats pulse duration, amplitude and shape as design variables that can create interactions absent from the original qudit system.

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.
