Dissipation-range fluid turbulence and thermal noise

D Bandak, N Goldenfeld, AA Mailybaev, G Eyink - Physical Review E, 2022 - APS
We revisit the issue of whether thermal fluctuations are relevant for incompressible fluid
turbulence and estimate the scale at which they become important. As anticipated by …

Turbulence in rotating Bose-Einstein condensates

J Amette Estrada, ME Brachet, PD Mininni - Physical Review A, 2022 - APS
Since the idea of quantum turbulence was first proposed by Feynman and later realized in
experiments of superfluid helium and Bose-Einstein condensates, much emphasis has been …

Quantum engines with interacting Bose-Einstein condensates

JA Estrada, F Mayo, AJ Roncaglia, PD Mininni - Physical Review A, 2024 - APS
We consider a quantum Otto cycle with an interacting Bose-Einstein condensate at finite
temperature. We present a procedure to evolve this system in time in three spatial …

From absolute equilibrium to Kardar–Parisi–Zhang crossover: A short review of recent developments

M Brachet - Chaos, Solitons & Fractals, 2022 - Elsevier
I first recall the theoretical background relevant to spectral truncation: absolute equilibrium in
helical flows and compressible effects. Thermalization phenomenology in Gross–Pitaevskii …

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 …

Self-similar evolution of wave turbulence in Gross-Pitaevskii system

Y Zhu, B Semisalov, G Krstulovic, S Nazarenko - Physical Review E, 2023 - APS
We study the universal nonstationary evolution of wave turbulence (WT) in Bose-Einstein
condensates (BECs). Their temporal evolution can exhibit different kinds of self-similar …

Direct evidence of a dual cascade in gravitational wave turbulence

S Galtier, SV Nazarenko - Physical Review Letters, 2021 - APS
We present the first direct numerical simulation of gravitational wave turbulence. General
relativity equations are solved numerically in a periodic box with a diagonal metric tensor …

G Wlazłowski, MMN Forbes, SR Sarkar, A Marek… - PNAS …, 2024 - academic.oup.com
Ultracold atoms provide a platform for analog quantum computer capable of simulating the
quantum turbulence that underlies puzzling phenomena like pulsar glitches in rapidly …

Dimensional measures of generalized entropy

V Zhdankin - Journal of Physics A: Mathematical and Theoretical, 2023 - iopscience.iop.org
Entropy is useful in statistical problems as a measure of irreversibility, randomness, mixing,
dispersion, and number of microstates. However, there remains ambiguity over the precise …

Abrupt transition between three-dimensional and two-dimensional quantum turbulence

NP Müller, ME Brachet, A Alexakis, PD Mininni - Physical Review Letters, 2020 - APS
We present numerical evidence of a critical-like transition in an out-of-equilibrium mean-field
description of a quantum system. By numerically solving the Gross-Pitaevskii equation we …
