Abstract

We consider an Yb-doped double-clad fiber laser in a unidirectional ring cavity containing a polarizer placed between two half-wave plates. Depending on the orientation of the phase plates, the laser operates in continuous, Q-switch, mode-lock or unstable self-pulsing regime. An experimental study of the stability of the mode locking regime is realized versus the orientation of the half-wave plates. A model for the stability of self-mode-locking and cw operation is developed starting from two coupled nonlinear Schrodinger equations in a gain medium. The model is reduced to a master equation in which the coefficients are explicitly dependent on the orientation angles of the phase plates. Analytical solutions are given together with their stability versus the angles.

Breathers across the Focusing-to-Defocusing Transition: From Diffraction-Like Dynamics to Talbot Carpets

We experimentally investigate fundamental unstable breather wave groups propagating across the transition from focusing to defocusing regimes. In hydrodynamics, this transition is realized through a rapid reduction in water depth over a short spatial interval. We demonstrate that the time-periodic Akhmediev breather develops a Talbot-like recurrence pattern in the defocusing regime, although only its initial stages are experimentally accessible. In contrast, the Peregrine breather exhibits qualitatively different behavior, characterized by oscillatory envelope dynamics. These oscillations can be understood as a purely linear phenomenon arising within the nonlinear Schrödinger framework when dispersion dominates over nonlinearity, as further confirmed by numerical simulations over extended propagation distances. The experimental observations agree closely with finite-depth nonlinear Schrödinger predictions across regimes with substantially different relative strengths of dispersion and nonlinearity. Our findings reveal a temporal analogue of diffraction and provide a foundation for exploring focusing-to-defocusing transitions in other nonlinear dispersive media.

Continuum mean-field theory of spatiotemporal pattern formation in a three-state active Potts model

We investigate the spatiotemporal dynamics of a three-state active Potts model with a cyclic transition bias. Starting from microscopic Glauber-type dynamics, we derive macroscopic continuum field equations through a spatial mean-field approximation. Linear stability and weakly nonlinear analyses reveal that increasing the coupling strength induces a Hopf bifurcation, near which the critical amplitude dynamics is described by the complex Ginzburg--Landau equation. In the spatially homogeneous limit, the system exhibits limit-cycle oscillations and ordered states, with an intermediate regime of bistability bounded by a $\mathbb{Z}_3$-symmetric heteroclinic bifurcation. In two dimensions, the system sustains stable rotating spiral waves. Using perturbation theory based on one-dimensional traveling fronts, we semianalytically predict the curvature-dependent propagation velocity of circular fronts, as well as the rotational angular velocity and pitch of spiral waves. Finally, we compare the continuum model with discrete Monte Carlo simulations to clarify the role of thermal fluctuations and evaluate the validity of the mean-field approximation.

Pattern selection and biomass shifts in a vegetation model with nonlocal competition and Allee activation

We study a single-species vegetation model in which a strong Allee effect acts locally and competition acts through a nonlocal kernel, and we describe the kernel with the one-parameter family of q-Gaussians, which goes from compact support to power-law tails. The local activation introduced by the Allee effect allows a finite-wavelength instability even when the Fourier transform of the kernel is positive, so Gaussian and heavy-tailed kernels can produce patterns. We derive in closed form the coefficients of the hexagonal amplitude equations and verify them against independent numerical steady states. The quadratic coefficient $Q$ results from the balance between the curvature of the local growth and the competitive inhibition at the pattern scale, and at onset its sign depends only on the fraction of the local activation that diffusion removes at the critical wavenumber. The same coefficient controls the morphology, since spots, labyrinths and gaps appear with pairwise competition only as $Q$ changes sign, and the amplitude equations predict the choice between hexagons and stripes in every simulated state in which the cubic truncation holds. It also controls the total biomass, which increases for spots and decreases for gaps.
