Experimental, numerical, and analytical velocity spectra in turbulent quantum fluid

CF Barenghi, VS L'vov… - Proceedings of the …, 2014 - National Acad Sciences
Turbulence in superfluid helium is unusual and presents a challenge to fluid dynamicists
because it consists of two coupled, interpenetrating turbulent fluids: the first is inviscid with …

Numerical studies of quantum turbulence

M Tsubota, K Fujimoto, S Yui - Journal of Low Temperature Physics, 2017 - Springer
We review numerical studies of quantum turbulence. Quantum turbulence is currently one of
the most important problems in low temperature physics and is actively studied for superfluid …

Introduction to quantum turbulence

CF Barenghi, L Skrbek… - Proceedings of the …, 2014 - National Acad Sciences
The term quantum turbulence denotes the turbulent motion of quantum fluids, systems such
as superfluid helium and atomic Bose–Einstein condensates, which are characterized by …

Quantum vortex reconnections

S Zuccher, M Caliari, AW Baggaley, CF Barenghi - Physics of fluids, 2012 - pubs.aip.org
We study reconnections of quantum vortices by numerically solving the governing Gross-
Pitaevskii equation. We find that the minimum distance between vortices scales differently …

[HTML][HTML] A new self-consistent approach of quantum turbulence in superfluid helium

L Galantucci, AW Baggaley, CF Barenghi… - The European Physical …, 2020 - Springer
We present the Fully cOUpled loCAl model of sUperfLuid Turbulence (FOUCAULT) that
describes the dynamics of finite temperature superfluids. The superfluid component is …

Magnus-force model for active particles trapped on superfluid vortices

A Griffin, V Shukla, ME Brachet, S Nazarenko - Physical Review A, 2020 - APS
Experimentalists use particles as tracers in liquid helium. The intrusive effects of particles on
the dynamics of vortices remain poorly understood. We implement a study of how basic, well …

Quasiclassical and ultraquantum decay of superfluid turbulence

AW Baggaley, CF Barenghi, YA Sergeev - Physical Review B—Condensed …, 2012 - APS
We address a question which, after a decade-long discussion, still remains open: what is the
nature of the ultraquantum regime of decay of quantum turbulence? The model developed in …

Coherent vortex structures in quantum turbulence

AW Baggaley, CF Barenghi, A Shukurov… - Europhysics …, 2012 - iopscience.iop.org
Quantum turbulence, easily generated in superfluid helium, consists of a disordered tangle
of thin, discrete vortex lines of quantised circulation which move in a fluid without viscosity. In …

Thermally and mechanically driven quantum turbulence in helium II

AW Baggaley, LK Sherwin, CF Barenghi… - Physical Review B …, 2012 - APS
In most experiments with superfluid helium, turbulence is generated thermally (by applying a
heat flux, as in thermal counterflow) or mechanically (by stirring the liquid). By modeling the …

Evolution of a superfluid vortex filament tangle driven by the Gross-Pitaevskii equation

A Villois, D Proment, G Krstulovic - Physical Review E, 2016 - APS
The development and decay of a turbulent vortex tangle driven by the Gross-Pitaevskii
equation is studied. Using a recently developed accurate and robust tracking algorithm, all …
