Liquid metal experiments on the helical magnetorotational instability
Frank Stefani, Gunter Gerbeth, Thomas Gundrum +3
The magnetorotational instability (MRI) plays an essential role in the formation of stars and black holes. By destabilizing hydrodynamically stable Keplerian flows, the MRI trigger…
History and results of the Riga dynamo experiments
Agris Gailitis, Gunter Gerbeth, Thomas Gundrum +3
On 11 November 1999, a self-exciting magnetic eigenfield was detected for the first time in the Riga liquid sodium dynamo experiment. We report on the long history leading to this…
Coexisting stochastic and coherence resonance in a mean-field dynamo model for Earth's magnetic field reversals
M. Fischer, F. Stefani, G. Gerbeth
Using a spherical symmetric mean field alpha^2-dynamo model for Earth's magnetic field reversals, we show the coexistence of the noise-induced phenomena coherence resonance and sto…
The integral equation approach to kinematic dynamo theory and its application to dynamo experiments in cylindrical geometry
Mingtian Xu, Frank Stefani, Gunter Gerbeth
The conventional magnetic induction equation that governs hydromagnetic dynamo action is transformed into an equivalent integral equation system. An advantage of this approach is t…
Experiments on the magnetorotational instability in helical magnetic fields
Frank Stefani, Thomas Gundrum, Gunter Gerbeth +3
The magnetorotational instability (MRI) plays a key role in the formation of stars and black holes, by enabling outward angular momentum transport in accretion disks. The use of co…
Experimental evidence for magnetorotational instability in a helical magnetic field
Frank Stefani, Thomas Gundrum, Gunter Gerbeth +4
A recent paper [R. Hollerbach and G. Rudiger, Phys. Rev. Lett. 95, 124501 (2005)] has shown that the threshold for the onset of the magnetorotational instability (MRI) in a Taylor-…
