Technological advances in controlling and manipulating fluids have enabled the
experimental realization of acoustic analogues of gravitational black holes. A flowing fluid …

Theoretical studies on wave turbulence predict that a purely classical system of random
waves can exhibit a process of condensation, which originates in the singularity of the …

Dispersive shock waves are fascinating phenomena occurring when nonlinearity
overwhelms linear effects, such as dispersion and diffraction. Many features of shock waves …

Abstract A (3+ 1)-dimensional Boiti–Boiti–Leon–Manna–Pempinelli equation is investigated,
which describes nonlinear wave propagations in incompressible fluid. A condition …

Turbulence is a challenging feature common to a wide range of complex phenomena.
Random fibre lasers are a special class of lasers in which the feedback arises from multiple …

The nonlinear Schrödinger equation, used to describe the dynamics of quantum fluids, is
known to be valid not only for massive particles but also for the propagation of light in a …

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 …

A landmark of statistical mechanics, spin-glass theory describes critical phenomena in
disordered systems that range from condensed matter to biophysics and social dynamics …

Ring dark and antidark solitons in nonlocal media are found. These structures have,
respectively, the form of annular dips or humps on top of a stable CW background, and exist …

Recent work has unveiled a new class of optical systems that can exhibit the characteristic
features of superfluidity. One such system relies on the repulsive photon-photon interaction …
