Structure of a single-quantum vortex in He-A
Riku Rantanen, Erkki Thuneberg, Vladimir Eltsov
We have performed numerical calculations of the structure of the single-quantum vortex in superfluid He-A. The GPU-accelerated large-scale numerical simulation is performed in…
Vortex-mediated relaxation of magnon BEC into light Higgs quasiparticles
S. Autti, P. J. Heikkinen, S. M. Laine +4
A magnon Bose-Einstein condensate in superfluid He is a fine instrument for studying the surrounding macroscopic quantum system. At zero temperature, the BEC is subject to a fe…
Two-parameter boundary condition applied to transverse acoustic impedance of a Fermi liquid
J. A. Kuorelahti, E. V. Thuneberg
We discuss surface scattering in terms of bidirectional reflectance distribution function. We formulate a boundary condition that in addition to diffuse and specular reflection has…
Fermi liquid theory applied to a film on an oscillating substrate
J. A. Kuorelahti, J. A. Tuorila, E. V. Thuneberg
We have studied the transmission of transverse oscillations through a thin Fermi liquid film, using Landau's Fermi liquid theory. Fermi liquid theory describes the dynamics of inte…
Asymptotic motion of a single vortex in a rotating cylinder
J. M. Karimäki, R. Hänninen, E. V. Thuneberg
We study numerically the behavior of a single quantized vortex in a rotating cylinder. We study in particular the spiraling motion of a vortex in a cylinder that is parallel to the…
Fermi liquid theory of Fermi-Bose mixtures
E. V. Thuneberg, T. H. Virtanen
We write down the basic equations of Fermi-liquid theory for mixtures of fermions and bosons, an example being 3He-4He mixtures at low temperatures. Basically the theory is identic…
