Modulation Instability and Wavenumber Bandgap Breathers in a Time Layered Phononic Lattice

Kavli Affiliate: Chiara Daraio | First 5 Authors: Christopher Chong, Brian Kim, Evelyn Wallace, Chiara Daraio, | Summary: We demonstrate the existence of wavenumber bandgap (q-gap) breathers in a time-periodic phononic lattice. These breathers are localized in time and periodic in space, and are the counterparts to the classical breathers found in spatially-periodic systems. We […]
