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.…
Nonlinear stabilization of chiral modes in space-time modulated parametric oscillators
Scott Lambert, Elise Jaremko, Jayson Paulose
Phase control of parametric modulation in coupled oscillator networks enables these networks to access dynamical states with desired spatiotemporal symmetries. Floquet theory-based…
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…
Space-time symmetry and nonreciprocal parametric resonance in mechanical systems
Abhijeet Melkani, Jayson Paulose
Linear mechanical systems with time-modulated parameters can harbor oscillations with amplitudes that grow or decay exponentially with time due to the phenomenon of parametric reso…
A Geometric Mapping from Rectilinear Material Orthotropy to Isotropy: Insights to Plates and Shells
Wenqian Sun, Cody Rasmussen, Roman Vetter +1
Orthotropic shell structures are ubiquitous in biology and engineering, from bacterial cell walls to reinforced domes. We present a rescaling transformation that maps an orthotropi…
Non-singular and singular flat bands in tunable acoustic metamaterials
Pragalv Karki, Jayson Paulose
Dispersionless flat bands can be classified into two types: (1) non-singular flat bands whose eigenmodes are completely characterized by compact localized states; and (2) singular…
