Helicity Conservation, and Twisted Seifert Surfaces for Superfluid Vortices
Hayder Salman
Starting from the continuum definition of helicity, we derive from first principles its different contributions for superfluid vortices. Our analysis shows that an internal twist c…

Helicity within the vortex filament model
R. Hänninen, N. Hietala, H. Salman
Kinetic helicity is one of the invariants of the Euler equations that is associated with the topology of vortex lines within the fluid. In superfluids, the vorticity is concentrate…

From Classical Fields to Two-Fluid Model of Superfluidity: Emergent Kinetics and Local Gauge Transformations
Hayder Salman, Natalia G. Berloff, Paul H. Roberts
The first successful macroscopic theory for the motion of superfluid helium was that of Lev Landau (1941) in which the fluid is modelled phenomenologically as an interpenetrating m…
