Kelvin-Helmholtz instability in 3He superfluids in zero temperature limit
V. B. Eltsov, J. J. Hosio, M. Krusius
In rotating 3He superfluids the Kelvin-Helmholtz (KH) instability of the AB interface has been found to follow the theoretical model above 0.4 Tc. A deviation from this dependence…
Rotating quantum wave turbulence
J. T. Mäkinen, S. Autti, P. J. Heikkinen +6
Rotating turbulence is ubiquitous in nature. Previous works suggest that such turbulence could be described as an ensemble of interacting inertial waves across a wide range of leng…
Andreev reflection in rotating superfluid He-B
V. B. Eltsov, J. J. Hosio, M. Krusius +1
Andreev reflection of quasiparticle excitations from quantized line vortices is reviewed in the isotropic B phase of superfluid He in the temperature regime of ballistic quasip…
Relaxation of Bose-Einstein Condensates of Magnons in Magneto-Textural Traps in Superfluid He-B
P. J. Heikkinen, S. Autti, V. B. Eltsov +3
In superfluid He-B externally pumped quantized spin-wave excitations or magnons spontaneously form a Bose-Einstein condensate in a 3-dimensional trap created with the order-par…
Thermal Detection of Turbulent and Laminar Dissipation in Vortex Front Motion
J. J. Hosio, V. B. Eltsov, M. Krusius
We report on direct measurements of the energy dissipated in the spin-up of the superfluid component of 3He-B. A vortex-free sample is prepared in a cylindrical container, where th…
Energy and angular momentum balance in wall-bounded superfluid turbulence
J. J. Hosio, V. B. Eltsov, P. J. Heikkinen +3
A superfluid in the absence of the viscous normal component should be the best realization of an ideal inviscid Euler fluid. As expressed by d'Alembert's famous paradox, an ideal f…
Quasiparticle scattering measurements of laminar and turbulent vortex flow in the spin-down of superfluid 3He-B
Jaakko Hosio, Vladimir Eltsov, Matti Krusius +1
The dynamics of quantized vortices is studied in superfluid 3He-B after a rapid stop of rotation. We use Andreev reflection of thermal excitations to monitor vortex motion with qua…
Turbulent Vortex Flow Responses at the AB Interface in Rotating Superfluid 3He-B
P. M. Walmsley, V. B. Eltsov, P. J. Heikkinen +3
In a rotating two-phase sample of 3He-B and magnetic-field stabilized 3He-A the large difference in mutual friction dissipation at 0.20 Tc gives rise to unusual vortex flow respons…
Propagation of thermal excitations in a cluster of vortices in superfluid 3He-B
J. J. Hosio, V. B. Eltsov, R. de Graaf +3
We describe the first measurement on Andreev scattering of thermal excitations from a vortex configuration with known density, spatial extent, and orientations in 3He-B superfluid.…
Textures of Superfluid 3He-B in Applied Flow and Comparison with Hydrostatic Theory
R. de Graaf, V. B. Eltsov, J. J. Hosio +2
Measurements of the order parameter texture of rotating superfluid 3He-B have been performed as a function of the applied azimuthal counterflow velocity down to temperatures of 0.2…
Super Stability of Laminar Vortex Flow in Superfluid 3He-B
V. B. Eltsov, R. de Graaf, P. J. Heikkinen +4
Vortex flow remains laminar up to large Reynolds numbers (Re~1000) in a cylinder filled with 3He-B. This is inferred from NMR measurements and numerical vortex filament calculation…
Self-localization of magnon Bose-Einstein condensates in the ground state and on excited levels: from harmonic to box-like trapping potential
S. Autti, Yu. M. Bunkov, V. B. Eltsov +5
Long-lived coherent spin precession of 3He-B at low temperatures around 0.2 Tc is a manifestation of Bose-Einstein condensation of spin-wave excitations or magnons in a magnetic tr…
Quartz Tuning Fork: Thermometer, Pressure- and Viscometer for Helium Liquids
R. Blaauwgeers, M. Blazkova, M. Clovecko +10
Commercial quartz oscillators of the tuning-fork type with a resonant frequency of ~32 kHz have been investigated in helium liquids. The oscillators are found to have at best Q val…
