Full-band reciprocal parametric amplification in coupled oscillator arrays
Benjamin Kauffman, Jayson Paulose
Parametric resonance provides a versatile mechanism to manipulate wave signals in time-modulated metamaterials, but typically operates within narrow wavelength or frequency ranges.…

Space-time Floquet operator: Non-reciprocity and fractional topology of space-time crystals
Abhijeet Melkani, Jayson Paulose
We introduce a space-time Floquet operator, a generalization of the conventional Floquet operator, that captures the long-time behavior of space-time crystals - systems where spati…
