Surface-induced vortex core restructuring in a spin-triplet superfluid
Riku Rantanen, Mikael Huppunen, Erkki Thuneberg +1
Observing the structure of quantized vortices can provide evidence for the pairing nature of a superfluid or superconductor and pinpoint its order parameter. Spin-triplet superflui…
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…
Square-well model for superconducting pair-potential
Erkki Thuneberg
We study Andreev reflection in a one-dimensional square-well pair-potential. We discuss the history of the model. The current-phase relation is presented as a sum over Matsubara fr…
Comment on "Ballistic SNS sandwich as a Josephson junction"
Erkki Thuneberg
The old problem of supercurrent in a long ballistic SNS Josephson junction is interpreted using a simple picture of the fermion energy levels in the normal and superconducting regi…
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…
Spin wave radiation from vortices in He-B
S. M. Laine, E. V. Thuneberg
We consider a vortex line in the B phase of superfluid He under uniformly precessing magnetization. The magnetization exerts torque on the vortex, causing its order parameter t…
