Visualization of quantum turbulence in superfluid He-B: Combined numerical/experimental study of Andreev reflection
Viktor Tsepelin, Andrew W. Baggaley, Yuri A. Sergeev +5
We present a combined numerical and experimental study of Andreev scattering from quantum turbulence in superfluid He-B at ultralow temperatures. We simulate the evolution of m…
Breaking the superfluid speed limit
D. I. Bradley, S. N. Fisher, A. M. Guénault +7
Coherent condensates appear as emergent phenomena in many systems, sharing the characteristic feature of an energy gap separating the lowest excitations from the condensate ground…
Probing Bogoliubov quasiparticles in superfluid He with a 'vibrating-wire like' MEMS device
M. Defoort, S. Dufresnes, S. L. Ahlstrom +11
We have measured the interaction between superfluid He-B and a micro-machined goalpost-shaped device at temperatures below . The measured damping follows well the the…
Dissipation of Quasiclassical Turbulence in Superfluid He
D. E. Zmeev, P. M. Walmsley, A. I. Golov +3
We compare the decay of turbulence in superfluid He produced by a moving grid to the decay of turbulence created by either impulsive spin-down to rest or by intense ion injecti…
Visualizing Pure Quantum Turbulence in Superfluid He: Andreev Reflection and its Spectral Properties
A. W. Baggaley, V. Tsepelin, C. F. Barenghi +4
Superfluid He-B in the zero-temperature limit offers a unique means of studying quantum turbulence by the Andreev reflection of quasiparticle excitations by the vortex flow fie…
Scattering length of Andreev reflection from quantized vortices in He-
Yuri A. Sergeev, Carlo F. Barenghi, Shaun N. Fisher +2
Andreev reflection of thermal quasiparticles from quantized vortices is an important technique to visualize quantum turbulence in low temperature He-. We revisit a problem o…
