Stokes drift and impurity transport in a quantum fluid
Umberto Giuriato, Giorgio Krstulovic, Miguel Onorato +1
Stokes drift is a classical fluid effect in which travelling waves transfer momentum to tracers of the fluid, resulting in a non-zero drift velocity in the direction of the incomin…
Stochastic motion of finite-size immiscible impurities in a dilute quantum fluid at finite temperature
Umberto Giuriato, Giorgio Krstulovic
The dynamics of an active, finite-size and immiscible impurity in a dilute quantum fluid at finite temperature is characterized by means of numerical simulations of the projected G…
Quantum vortex reconnections mediated by trapped particles
Umberto Giuriato, Giorgio Krstulovic
Reconnections between quantum vortex filaments in presence of trapped particles are investigated using numerical simulations of the Gross--Pitaevskii equation. Particles are descri…
Active and finite-size particles in decaying quantum turbulence at low temperature
Umberto Giuriato, Giorgio Krstulovic
The evolution of a turbulent tangle of quantum vortices in presence of finite-size active particles is studied by means of numerical simulations of the Gross-Pitaevskii equation. P…
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…
Interaction between active particles and quantum vortices leading to Kelvin wave generation
Umberto Giuriato, Giorgio Krstulovic
One of the main features of superfluids is the presence of topological defects with quantised circulation. These objects are known as quantum vortices and exhibit a hydrodynamic be…
Clustering and phase transitions in a 2D superfluid with immiscible active impurities
Umberto Giuriato, Giorgio Krstulovic, Davide Proment
Phase transitions of a finite-size two-dimensional quantum fluid of bosons in presence of impurities are studied by using the truncated Gross-Pitaevskii model. Impurities are descr…
