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 …

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 …

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 …

I first recall the theoretical background relevant to spectral truncation: absolute equilibrium in
helical flows and compressible effects. Thermalization phenomenology in Gross–Pitaevskii …

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 …

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 …

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 …

Ultracold atoms provide a platform for analog quantum computer capable of simulating the
quantum turbulence that underlies puzzling phenomena like pulsar glitches in rapidly …

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 …

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 …
