Gap solitons in Bragg gratings with a harmonic superlattice
K. Yagasaki, I. M. Merhasin, B. A. Malomed +2
Solitons are studied in a model of a fiber Bragg grating (BG) whose local reflectivity is subjected to periodic modulation. The superlattice opens an infinite number of new bandgap…
Discrete embedded solitons
Kazuyuki Yagasaki, Alan R. Champneys, Boris A. Malomed
We address the existence and properties of discrete embedded solitons (ESs), i.e., localized waves existing inside the phonon band in a nonlinear dynamical-lattice model. The model…
Accumulation of embedded solitons in systems with quadratic nonlinearity
B. A. Malomed, T. Wagenknecht, A. R. Champneys +1
Previous numerical studies have revealed the existence of embedded solitons (ESs) in a class of multi-wave systems with quadratic nonlinearity, families of which seem to emerge fro…
Boundary effects and the onset of Taylor vortices
A. M. Rucklidge, A. R. Champneys
It is well established that the onset of spatially periodic vortex states in the Taylor-Couette flow between rotating cylinders occurs at the value of Reynold's number predicted by…
