Periodic and quasiperiodic traveling waves in nonlinear lattices with odd elasticity
Andrus Giraldo, Stefan Ruschel, Behrooz Yousefzadeh
Discrete nonlinear systems support a rich variety of localized and extended wave phenomena, with their dynamics sensitively dependent on the symmetries of the underlying interactio…
Parametric Instability in Discrete Models of Spatiotemporally Modulated Materials
Jiuda Wu, Behrooz Yousefzadeh
We investigate the phenomenon of parametric instability in discrete models of spatiotemporally modulated materials. These materials are celebrated in part because they exhibit nonr…
Phase-preserving nonreciprocal dynamics in coupled nonlinear oscillators
Ali Kogani, Behrooz Yousefzadeh
Nonreciprocity is most commonly associated with a large difference in the transmitted energy when the locations of the source and receiver are interchanged. This energy bias is acc…
Unilateral vibration transmission in mechanical systems with bilinear coupling
Ali Kogani, Behrooz Yousefzadeh
Unilateral transmission refers to the scenario in which the waves transmitted through a system remain in pure tension or pure compression. This transmission phenomenon may occur in…
Nonreciprocal Phase Shifts in Spatiotemporally Modulated Systems
Jiuda Wu, Behrooz Yousefzadeh
Materials and devices subject to spatiotemporal modulation of their effective properties have a demonstrated ability to support nonreciprocal transmission of waves. Most notably, s…
