Linear and nonlinear dynamics of isospectral granular chains
R. Chaunsali, H. Xu, J. Yang +1
We study the dynamics of isospectral granular chains that are highly tunable due to the nonlinear Hertz contact law interaction between the granular particles. The system dynamics…
Nonlinear Low-to-High Frequency Energy Cascades in Diatomic Granular Crystals
E. Kim, R. Chaunsali, H. Xu +4
We study wave propagation in strongly nonlinear 1D diatomic granular crystals under an impact load. Depending on the mass ratio of the `light' to `heavy' beads, this system exhibit…
Traveling Waves and their Tails in Locally Resonant Granular Systems
H. Xu, P. G. Kevrekidis, A. Stefanov
In the present study, we revisit the theme of wave propagation in locally resonant granular crystal systems, also referred to as Mass-in-Mass systems. We use 3 distinct approaches…
Generalized Dimers and their Stokes-variable Dynamics
H. Xu, P. G. Kevrekidis, A. Saxena
In the present work, we generalize the setting of dimers with potential gain and loss which have been extensively considered recently in -symmetric contexts. We cons…
Nonlinear PT-symmetric models bearing exact solutions
H. Xu, P. G. Kevrekidis, Q. Zhou +3
We study the nonlinear Schrdinger equation with a PT-symmetric potential. Using a hydrodynamic formulation and connecting the phase gradient to the field amplitude, allow…
