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 …

Quantum droplets represent a novel state of matter achieved by tailoring a binary Bose–
Einstein condensate, where the collapse driven by self-attraction is arrested by quantum …

We introduce one-and two-dimensional (1D and 2D) models of parity-time (PT)-symmetric
couplers with the mutually balanced linear gain and loss applied to the two cores and cubic …

We investigate the existence of self-trapped nonlinear waves with multiple phase
singularities. Working with the cubic-quintic nonlinear Schrödinger equation, we focus on …

We experimentally investigate the two-dimensional condensate (optical dropletlike) soliton
formation and dynamics of the generated signal and probe beams in four-wave mixing …

We discuss the stability of topological quantum droplets with the shape of two-dimensional
soliton rings endowed with angular momentum that stem from a symmetric binary mixture in …

We study topologically charged propagation-invariant eigenstates of the 1+ 2-dimensional
Schrödinger equation with a cubic (focusing)–quintic (defocusing) nonlinear term. First, we …

We study the cubic-(focusing-) quintic (defocusing) nonlinear Schrödinger equation in two
transverse dimensions. We discuss a family of stationary traveling waves, including …

We discuss the dynamics of fundamental Gaussian beams launched in saturable and
nonlocal nonlinear media. Solely in the presence of a self-focusing saturable nonlinearity …

Simulated three-dimensional quantum wave functions (or probability density distributions, in
general), Ψ (x, t), are often represented graphically as smooth isocontours or with 2 …
