Modulational Instability in Nonlinearity-Managed Optical Media
Martin Centurion, Mason A. Porter, Ye Pu +3
We investigate analytically, numerically, and experimentally the modulational instability in a layered, cubically-nonlinear (Kerr) optical medium that consists of alternating layer…
Dark Solitons in Discrete Lattices: Saturable versus Cubic Nonlinearities
E. P. Fitrakis, P. G. Kevrekidis, H. Susanto +1
In the present work, we study dark solitons in dynamical lattices with the saturable nonlinearity and compare them with those in lattices with the cubic nonlinearity. This comparis…
Modulational instability in a layered Kerr medium: Theory and Experiment
Martin Centurion, Mason A. Porter, Ye Pu +3
We present the first experimental investigation of modulational instability in a layered Kerr medium. The particularly interesting and appealing feature of our configuration, consi…
Modulated Amplitude Waves in Collisionally Inhomogeneous Bose-Einstein Condensates
Mason A. Porter, P. G. Kevrekidis, Boris A. Malomed +1
We investigate the dynamics of an effectively one-dimensional Bose-Einstein condensate (BEC) with scattering length subjected to a spatially periodic modulation, $a=a(x)=a(x+L)…
Symmetry Breaking in Symmetric and Asymmetric Double-Well Potentials
G. Theocharis, P. G. Kevrekidis, D. J. Frantzeskakis +1
Motivated by recent experimental studies of matter-waves and optical beams in double well potentials, we study the solutions of the nonlinear Schrödinger equation in such a context…
X,Y,Z-Waves: Extended Structures in Nonlinear Lattices
P. G. Kevrekidis, J. Gagnon, D. J. Frantzeskakis +1
Motivated by recent experimental and theoretical results on optical X-waves, we propose a new type of waveforms in 2D and 3D discrete media -- multi-legged extended nonlinear struc…
