Discrete Breathers in a Forced-Damped Array of Coupled Pendula:<? format?> Modeling, Computation, and Experiment
In this work, we present a mechanical example of an experimental realization of a stability
reversal between on-site and intersite centered localized modes. A corresponding …

Damped-driven granular chains: An ideal playground for dark breathers and multibreathers
By applying an out-of-phase actuation at the boundaries of a uniform chain of granular
particles, we demonstrate experimentally that time-periodic and spatially localized structures …

Quantum signatures of an oscillatory instability in the Bose-Hubbard trimer
P Jason, M Johansson, K Kirr - Physical Review E—Statistical, Nonlinear, and …, 2012 - APS
We study the Bose-Hubbard model for three sites in a symmetric, triangular configuration
and search for quantum signatures of the classical regime of oscillatory instabilities, known …
