Discrete breathers at the interface between a diatomic and monoatomic granular chain
C. Hoogeboom, G. Theocharis, P. G. Kevrekidis
In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoa…
Tunable Vibrational Band Gaps in One-Dimensional Diatomic Granular Crystals with Three-Particle Unit Cells
N. Boechler, J. Yang, G. Theocharis +2
We investigate the tunable vibration filtering properties of one-dimensional diatomic granular crystals composed of arrays of stainless steel spheres and cylinders interacting via…
Intrinsic Energy Localization through Discrete Gap Breathers in One-Dimensional Diatomic Granular Crystals
G. Theocharis, N. Boechler, P. G. Kevrekidis +3
We present a systematic study of the existence and stability of discrete breathers that are spatially localized in the bulk of a one-dimensional chain of compressed elastic beads t…
Dark solitons in cigar-shaped Bose-Einstein condensates in double-well potentials
S. Middelkamp, G. Theocharis, P. G. Kevrekidis +2
We study the statics and dynamics of dark solitons in a cigar-shaped Bose-Einstein condensate confined in a double-well potential. Using a mean-field model with a non-cubic nonline…
