Revisiting Multi-breathers in the discrete Klein-Gordon equation: A Spatial Dynamics Approach
Ross Parker, Jesús Cuevas-Maraver, P. G. Kevrekidis +1
We consider the existence and spectral stability of multi-breather structures in the discrete Klein-Gordon equation, both for soft and hard symmetric potentials. To obtain analytic…
Moving discrete breathers in a -FPU lattice revisited
H. Duran, J. Cuevas-Maraver, P. G. Kevrekidis +1
In the present work we revisit the existence, stability and dynamical properties of moving discrete breathers in -FPU lattices. On the existence side, we propose a numerical pro…
Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
F. Palmero, L. Q. English, J. Cuevas-Maraver +1
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies…
Solitary waves in the Ablowitz-Ladik equation with power-law nonlinearity
J. Cuevas-Maraver, P. G. Kevrekidis, B. A. Malomed +1
We introduce a generalized version of the Ablowitz-Ladik model with a power-law nonlinearity, as a discretization of the continuum nonlinear Schrödinger equation with the same type…
Propagation studies for the construction of atomic macro-coherence in dense media as a tool to investigate neutrino physics
J. Martín Vaquero, J. Cuevas-Maraver, A. Peralta Conde
In this manuscript we review the possibility of inducing large coherence in a macroscopic dense target by using adiabatic techniques. For this purpose we investigate the degradatio…
Rogue Waves in Ultracold Bosonic Seas
E. G. Charalampidis, J. Cuevas-Maraver, D. J. Frantzeskakis +1
In this work, we numerically consider the initial value problem for nonlinear Schrödinger (NLS) type models arising in the physics of ultracold boson gases, with generic Gaussian w…
Impulse-induced generation of stationary and moving discrete breathers in nonlinear oscillator networks
J. Cuevas-Maraver, R. Chacón, F. Palmero
We study discrete breathers in prototypical nonlinear oscillator networks subjected to non-harmonic zero-mean periodic excitations. We show how the generation of stationary and mov…
