Free superfluid helium droplets constitute a versatile medium for a diverse range of
experiments in physics and chemistry that extend from studies of the fundamental laws of …

Complex structures, consisting of a large number of interacting subsystems, have the ability
to self-organize and evolve, when the scattering of energy coming from the outside ensures …

Generic scaling laws, such as Kolmogorov's 5/3 law, are milestone achievements of
turbulence research in classical fluids. For quantum fluids such as atomic Bose–Einstein …

We investigate the thermal counterflow of the superfluid He 4 by numerically simulating
three-dimensional fully coupled dynamics of the two fluids, namely quantized vortices and a …

This paper is concerned with thermal counterflow in superfluid He 4, particularly with the
motion of the normal component at small heat fluxes when this motion is believed to be …

Thermal counterflow of superfluid, to ensure the existence of sufficiently dense tangles of
quantized vortices. Within the investigated parameter range, we observe that the particles …

Transient heat transfer in superfluid He 4 (He II) is a complex process that involves the
interplay of the unique counterflow heat-transfer mode, the emission of second-sound …

A sudden loss of vacuum can be catastrophic for superconducting particle accelerators. In
such an event, air leaks into the liquid-helium-cooled accelerator beamline tube and …

Despite being a quantum two-fluid system, superfluid helium-4 (He II) is observed to behave
similarly to classical fluids when a flow is generated by mechanical forcing. This similarity …

Historically, there has been little faith in particle tracking velocimetry (PTV) as a tool to make
quantitative measurements of thermal counterflow in He II, since tracer particle motion is …
