By analytical and numerical methods we investigate the late stage deposition of binary mixtures of oriented “superdisks” on a plane. Superdisks are objects bounded by Lame curves | x | 2 p + | y | 2 p = 1 , where deformation parameter p controls

In a recent paper [A. Alberucci, C. Jisha, N. Smyth, and G. Assanto, Phys. Rev. A 91, 013841 (2015)], Alberucci et al. have studied the propagation of bright spatial solitary waves in highly nonlocal media. We find that the main results in that and r

The self-structuring of laser light in an artificial optical medium composed of a colloidal suspension of nanoparticles is demonstrated using variational and numerical methods extended to dissipative systems. In such engineered materials, competing n

Two-dimensional dissipative solitons are described by the complex Ginzburg–Landau equation, with cubic-quintic nonlinearity compensating for diffraction, while linear and nonlinear losses are simultaneously balanced by the gain. Vortices with zero

The generation and nonlinear dynamics of one-dimensional optical dissipative solitonic pulses are examined. The variational method is extended to complex dissipative systems, in order to obtain steady state solutions of the (1 + 1)-dimensional comple

We apply the variational approach to solitons in highly nonlocal nonlinear media in D = 1, 2, 3 dimensions. We compare results obtained by the variational approach with those obtained by the accessible soliton approximation, by considering the same s

International audience; We propose a complex Ginzburg-Landau equation (CGLE) with localized linear gain as a two-dimensional model for pattern formation proceeding via spontaneous breaking of the axial symmetry. Starting from steady-state solutions p

It is shown that delocalized vortex solitons in relativistic pair plasmas with small temperature asymmetries can be unstable for intermediate intensities of the background electromagnetic field. Instability leads to the generation of ever-expanding c

Efficient and accurate numerical solving of partial differential equations (PDE) is essential for many problems in science and engineering. In this paper we discuss spectral symplectic methods with different numerical accuracy on example of Nonlinear
