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…
Inferring basic parameters of the geodynamo from sequences of polarity reversals
Michael Fischer, Gunter Gerbeth, Andre Giesecke +1
The asymmetric time dependence and various statistical properties of polarity reversals of the Earth's magnetic field are utilized to infer some of the most essential parameters of…
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…
Determining role of Krein signature for 3D Arnold tongues of oscillatory dynamos
Oleg N. Kirillov, Uwe Guenther, Frank Stefani
Using a homotopic family of boundary eigenvalue problems for the mean-field -dynamo with helical turbulence parameter and homotopy parameter , we…
