During the last decade, density function theory (DFT) in its static and dynamic time
dependent forms, has emerged as a powerful tool to describe the structure and dynamics of …

Turbulence in a superfluid in the zero-temperature limit consists of a dynamic tangle of
quantized vortex filaments. Different types of turbulence are possible depending on the level …

A promising technology concept for sub-GeV dark matter detection is described, in which
low-temperature microcalorimeters serve as the sensors and superfluid He 4 serves as the …

Cryogenic flow visualization techniques have been proved in recent years to be a very
powerful experimental method to study superfluid turbulence. Micron-sized solid particles …

We describe a technique, using thin lines of triplet-state He 2* molecular tracers created by
femtosecond-laser field ionization of helium atoms, for visualizing the flow of the normal fluid …

Quantum vortices are a core element of superfluid dynamics and elusively hold the keys to
our understanding of energy dissipation in these systems. We show that we are able to …

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 model the superfluid flow of liquid helium over the rough surface of a wire (used to
experimentally generate turbulence) profiled by atomic force microscopy. Numerical …

Molecules immersed in liquid helium are excellent probes of superfluidity. Their electronic,
vibrational, and rotational dynamics provide valuable clues about the superfluid at the …

In classical viscous fluids, turbulent eddies are known to be responsible for the rapid
spreading of embedded particles. However, in inviscid quantum fluids where the turbulence …
