Kolmogorov and Kelvin Wave Cascades in a Generalized Model for Quantum Turbulence
The three-dimensional visualisation above shows a close up of the initial condition used in this work. The red low-density isosurface correspond to quantum vortex lines whereas the greenish rendering are density fluctuations about the bulk value.

Sound Emission in Vortex Reconnections made the Cover of PRL
Quantum vortices are one of the most important excitations of a superfluid. Such vortices behaves in many aspects as they classical counterpart. They reconnect changing the topology of the flow and transferring energy along scales.

New paper on quantum vortex reconnections mediated by particles published in Physical Review B
Particles are used in superfluid to visualise quantum vortices, they get trapped inside vortices, and we can follow their dynamics. Quantum vortices can reconnect, and particles are an essential tool to study the process.
