Quantum turbulence shares many similarities with classical turbulence in the isotropic and homogeneous case, despite the inviscid and quantized nature of its vortices. However, when quantum fluids are subjected to rotation, their turbulent ...

In this work, we analyse the evolution of four vortex configurations, namely, dipole, plasma, cluster and lattice, using the two-dimensional mean-field Gross-Pitaevskii equation, focusing on their dynamical decay and approach to the equilib...

The turbulence dynamics of dusty plasma flows, governed by strong long-range Coulomb interactions between particles, remains inadequately understood. In this paper, we simulate two-dimensional (2D) (KHI) and (RTI) turbulence in dusty plasma...

Strongly nonlinear dynamics, from fluid turbulence to quantum chromodynamics (QCD), has long constituted some of the most challenging problems in theoretical physics. This review describes a unified theoretical framework, the loop space cal...

We derive an analytic solution for the density of a passive scalar in decaying homogeneous turbulence, in the limit of high Reynolds number and fixed Schmidt number. The velocity statistics are described by the Euler ensemble, previously ob...

The long-time evolution of decaying homogeneous turbulence is a fundamental building block of the theory and modeling of turbulence. We investigate the problem by using a comprehensive suite of direct numerical simulations. The simulations ...

The extent to which equilibrium statistical theory is applicable to driven dissipative dynamics remains an important open question in many systems. We use extensive direct numerical simulations (DNS) of the incompressible two-dimensional (2...

In studies of turbulence, there has been extensive use of physical quantities such as energy transfers and structure functions. We examine whether these quantities can be useful in understanding problems of domain growth or coarsening, as m...

We discuss phenomenology associated with turbulent hydrodynamics in quantum fluids from a condensed-matter perspective. We begin with weakly interacting superfluids, often modelled by a mean-field theory governed by the Gross-Pitaevskii (GP...

We present a review of results concerning the properties of scales larger than the forcing scale in turbulent flows. In three-dimensional turbulence, when the power driving the flow is injected at a well-defined scale, the injection scale s...
