Capture and release of quantum vortices using mechanical devices in low-temperature superfluids
Sanjay Shukla, Giorgio Krstulovic, Rahul Pandit
We show that the Gross-Pitaevskii equation coupled with the wave equation for a wire (GP-W) provides a natural theoretical framework for understanding recent experiments employing…
Self-similar evolution of wave turbulence in Gross-Pitaevskii system
Ying Zhu, Boris Semisalov, Giorgio Krstulovic +1
We study the universal non-stationary evolution of wave turbulence (WT) in Bose-Einstein condensates (BECs). Their temporal evolution can exhibit different kinds of self-similar be…
Kelvin waves, mutual friction, and fluctuations in the Gross-Pitaevskii model
Giorgio Krstulovic, Marc E. Brachet
In this work we first briefly review some of the mutual friction effects on vortex lines and rings that were obtained in the context of the truncated Gross-Pitaevskii equation in r…
Energy spectrum of two-dimensional acoustic turbulence
Adam Griffin, Giorgio Krstulovic, Victor L'vov +1
We report an exact unique constant-flux power-law analytical solution of the wave kinetic equation for the turbulent energy spectrum, …
Critical velocity for vortex nucleation and roton emission in a generalized model for superfluids
Nicolás P. Müller, Giorgio Krstulovic
We study numerically the process of vortex nucleation at the wake of a moving object in superfluids using a generalized and non-local Gross-Pitaevskii model. The non-local potentia…
Comment on "Theoretical analysis of quantum turbulence using the Onsager ideal turbulence theory''
Giorgio Krstulovic, Victor L'vov, Sergey Nazarenko
In a recent paper [T. Tanogami Phys. Rev. E 103, 023106 ] proposes a scenario for quantum turbulence where the energy spectrum at scales smaller than the inter-vortex distance is d…
Kolmogorov and Kelvin wave cascades in a generalized model for quantum turbulence
Nicolás Pablo Müller, Giorgio Krstulovic
We performed numerical simulations of decaying quantum turbulence by using a generalized Gross-Pitaevskii equation, that includes a beyond mean field correction and a nonlocal inte…
Irreversible dynamics of vortex reconnections in quantum fluids
Alberto Villois, Davide Proment, Giorgio Krstulovic
We statistically study vortex reconnections in quantum fluids by evolving different realizations of vortex Hopf links using the Gross--Pitaevskii model. Despite the time-reversibil…
Inhomogeneous distribution of particles in co-flow and counterflow quantum turbulence
Juan Ignacio Polanco, Giorgio Krstulovic
Particles are today the main tool to study superfluid turbulence and visualize quantum vortices. In this work, we study the dynamics and the spatial distribution of particles in co…
How trapped particles interact with and sample superfluid vortex excitations
Umberto Giuriato, Giorgio Krstulovic, Sergey Nazarenko
Particles have been used for more than a decade to visualize and study the dynamics of quantum vortices in superfluid helium. In this work we study how the dynamics of a collection…
Grid superfluid turbulence and intermittency at very low temperature
Giorgio Krstulovic
Low-temperature grid generated turbulence is investigated by using numerical simulations of the Gross-Pitaevskii equation. The statistics of regularized velocity increments are stu…
Kelvin-wave cascade and dissipation in low-temperature superfluids vortices
Giorgio Krstulovic
We study the statistical properties of the Kelvin waves propagating along quantized superfluid vortices driven by the Gross-Pitaevskii equation. No artificial forcing or dissipatio…
