Exploring Interacting Bose Gases in and out of Equilibrium
… equilibrium, which feature ties to nonlinear wave phenomena. Highlights of our experiments include the direct measurement of turbulent-cascade fluxes, which (alongside realizing a tuneable dissipation scale) allow us to demonstrate the zeroth law of turbulence, and the first observation of …

Hydrodynamics and sedimentary structures of antidunes in gravel and sand mixtures
… turbulent flow structure within the standing waves above antidunes and to record the sedimentary response of a loose mobile bed that constituted the antidunes. The first suite of experiments used Acoustic Doppler Velocimetry (ADV) to quantify and characterise the flow structure above fixed …

Strongly Nonlinear Phenomena and Singularities in Optical, Hydrodynamic and Biological Systems
… in a $2$D problem: it is well-known that collapse in $2$D NLSE is radially symmetric and introducing radial variable $r = \\sqrt{x^2 + y^2}$ the problem becomes effectively one-dimensional. If we expand the interval spanned by $r$ from $[0,+\\infty)$ to $(-\\infty,+\\infty)$ and continue …
