We analyze the properties and stability of two-color discrete localized modes in arrays of channel waveguides where tunable quadratic nonlinearity is introduced as a nonlinear defect by periodic poling of a single waveguide ...

We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...

It is shown that in a current-carrying cylindrical plasma with a free boundary, viscosity and thermal conductivity can lead to large scale steady convection. The physical situation is identical to the case when the plasma ...

Chiral symmetry breaking at finite baryon density is usually discussed in the context of quark matter, i.e. a system of deconfined quarks. Many systems like stable nuclei and neutron stars however have quarks confined ...

Recent experimental and theoretical advances in the creation and description of bright matter wave solitons are reviewed. Several aspects are taken into account, including the physics of soliton train formation as the ...

The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...

© 2014 American Physical Society. We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an electron in ...

We study the dynamics of discrete vector solitons in arrays of weakly coupled birefringent optical waveguides with cubic nonlinear response. We start with a modulational instability analysis, followed by approximate ...
