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…
Triple-core structure of the double-core vortex in superfluid He-B
Riku Rantanen
The order parameter of superfluid He involves nine complex components, and the multicomponent structure allows quantized vortices in superfluid He to have complicated cores…
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…
Competition of vortex core structures in superfluid He-B
Riku Rantanen, Vladimir Eltsov
Among vortex structures identified so far in superfluid He-B, the most common are the A-phase-core vortex and the double-core vortex. According to earlier numerical calculation…
