Helicity oscillations in Rayleigh-Bénard convection of liquid metal in a cell with aspect ratio 0.5
R. Mitra, F. Stefani, V. Galindo +4
In this paper, we present numerical and experimental results on helicity oscillations in a liquid-metal Rayleigh-Bénard (RB) convection cell, with an aspect ratio of 0.5. We find t…

The Tayler instability at low magnetic Prandtl numbers: Chiral symmetry breaking and synchronizable helicity oscillations
F. Stefani, V. Galindo, A. Giesecke +2
The current-driven, kink-type Tayler instability (TI) is a key ingredient of the Tayler-Spruit dynamo model for the generation of stellar magnetic fields, but is also discussed as…
