We report on the formation of a dispersive shock wave in a nonlinear optical medium. We monitor the evolution of the shock by tuning the incoming beam power. The experimental observations for the position and intensity of the solitonic edge of the shock, as well as the location of the nonlinear oscillations are well described by recent developments of Whitham modulation theory. Our work constitutes a detailed and accurate benchmark for this approach. It opens exciting possibilities to engineer…

Spin-Injection-Generated Shock Waves and Solitons in a Ferromagnetic Thin Film
Unsteady nonlinear magnetization dynamics are studied in an easy-plane ferromagnetic channel subject to spin injection at one edge. The Landau–Lifshitz equation is known to support steady-state
Non-equilibrium pre-thermal states in a two-dimensional photon fluid
Thermalization is the dynamical process by which a many-body system evolves toward a thermal equilibrium state that maximizes its entropy. In certain cases, however, the establishment of thermal
Analogue gravitational field from nonlinear fluid dynamics
The dynamics of sound in a fluid is intrinsically nonlinear. We derive the consequences of this fact for the analogue gravitational field experienced by sound waves, by first describing generally how

Spin-orbit-coupled fluids of light in bulk nonlinear media
We show that nonparaxial polarized light beams propagating in a bulk nonlinear Kerr medium naturally exhibit a coupling between the motional and the polarization degrees of freedom, realizing a

Wave breaking and formation of dispersive shock waves in a defocusing nonlinear optical material
We theoretically describe the quasi one-dimensional transverse spreading of a light pulse propagating in a nonlinear optical material in the presence of a uniform background light intensity. For
Experimental Generation of Riemann Waves in Optics: A Route to Shock Wave Control.
TLDR
The first observation of Riemann (simple) waves is reported, which play a crucial role for understanding the dynamics of any shock-bearing system, by properly tailoring the phase of an ultrashort light pulse injected into a highly nonlinear fiber.
Shock waves in disordered media.
TLDR
The way the shock point is affected by the amount of disorder and scales with wave amplitude is characterized and evidence for the existence of a phase diagram in terms of nonlinearity and amount of randomness is reported.
Shock wave generation triggered by a weak background in optical fibers.
TLDR
The background allows the background to strongly enhance the extension and contrast of the oscillatory wave train inherent to the dispersive shock, and the dynamics of the process are explained from spectro-temporal representations.

TLDR
The results show evidence for a critical transition of the dispersive shock into a self-cavitating state and a fully quantitative test of the Whitham modulation theory applied to the universal defocusing nonlinear Schrödinger equation.

TLDR

TLDR
This work investigates the formation of collisionless shocks along the spatial profile of a Gaussian laser beam propagating in nonlocal nonlinear media for defocusing nonlinearity and focuses on the patterns observed in a thermal defocusing medium.
