There is growing physical and mathematical interest in the hydrodynamics of
dissipationless/dispersive media. Since GB Whitham's seminal publication fifty years ago …

Optical fibres are favourable tabletop laboratories to investigate both coherent and
incoherent nonlinear waves. In particular, exact solutions of the one-dimensional nonlinear …

We report optical experiments allowing us to investigate integrable turbulence in the
focusing regime of the one-dimensional nonlinear Schrödinger equation (1D NLSE). In …

One of the most controversial phenomena in nonlinear dynamics is the reappearance of
initial conditions. Celebrated as the Fermi-Pasta-Ulam-Tsingou problem, the attempt to …

We investigate the temporal photonic analogue of the dam-break phenomenon for shallow
water by exploiting a fiber optics setup. We clearly observe the decay of the steplike input …

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 …

Dissipative Kerr soliton generation in chip-scale nonlinear resonators has recently observed
remarkable advances, spanning from massively parallel communications, to self-referenced …

In hydrodynamics, vortex generation upon the transition from smooth laminar flows to
turbulence is generally accompanied by increased dissipation. However, vortices in the …

Light flow in nonlinear media can exhibit quantum hydrodynamical features which are
profoundly different from those of classical fluids. Here, we show that a rather extreme …

We observe the dispersive breaking of cosine-type long waves [Phys. Rev. Lett. 15, 240
(1965)] in shallow water, characterizing the highly nonlinear “multisoliton” fission over …
