Effect of boundary condition on Kapitza resistance between superfluid He-B and sintered metal
S. Autti, A. M. Guénault, R. P. Haley +7
Understanding the temperature dependence of thermal boundary resistance, or Kapitza resistance, between liquid helium and sintered metal has posed a problem in low temperature phys…
Fundamental dissipation due to bound fermions in the zero-temperature limit
S. Autti, R. P. Haley, A. Jennings +7
The ground state of a fermionic condensate is well protected against perturbations in the presence of an isotropic gap. Regions of gap suppression, surfaces and vortex cores which…
Multimode probing of superfluid by tuning forks
A. Guthrie, R. P. Haley, A. Jennings +9
Flexural mode vibrations of miniature piezoelectric tuning forks (TF) are known to be highly sensitive to superfluid excitations and quantum turbulence in and $\mat…
Orbitropic Effect in Superfluid He B-phase boundaries
M. Arrayás, R. Haley, G. R. Pickett +1
In this work we study the influence of orbital viscosity on the dynamics of the order parameter texture in the superfluid B-phase of He near a moving bounda ry. Based on the re…
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…
