Nonlinear Localized Modes in Two-Dimensional Hexagonally-Packed Magnetic Lattices
C. Chong, Yifan Wang, Donovan Marechal +6
We conduct an extensive study of nonlinear localized modes (NLMs), which are temporally periodic and spatially localized structures, in a two-dimensional array of repelling magnets…
Tuning frequency band gaps of tensegrity metamaterials with local and global prestress
Ada Amendola, Anastasiia Krushynska, Chiara Daraio +2
This work studies the acoustic band structure of tensegrity metamaterials, and the possibility to tune the dispersion relation of such systems by playing with local and global pres…
Nonlinear Excitations in Magnetic Lattices with Long-Range Interactions
Miguel Molerón, C. Chong, Alejandro J. Martínez +3
We study - experimentally, theoretically, and numerically - nonlinear excitations in lattices of magnets with long-range interactions. We examine breather solutions, which are spat…
Complete Delocalization in a Defective Periodic Structure
Behrooz Yousefzadeh, Chiara Daraio
We report on the existence of stable, completely delocalized response regimes in a nonlinear defective periodic structure. In this state of complete delocalization, despite the pre…
Time- and space-variant wave transmission in helicoidal phononic crystals
F. Li, C. Chong, J. Yang +2
We present a dynamically tunable mechanism of wave transmission in 1D helicoidal phononic crystals in a shape similar to DNA structures. These helicoidal architectures allow slante…
Wave mitigation in ordered networks of granular chains
Andrea Leonard, Laurent Ponson, Chiara Daraio
We study the propagation of stress waves through ordered 2D networks of granular chains. The quasi-particle continuum theory employed captures the acoustic pulse splitting, bending…
