Why dynamos are prone to reversals
Frank Stefani, Gunter Gerbeth, Uwe Guenther +1
In a recent paper (Phys. Rev. Lett. 94 (2005), 184506; physics/0411050) it was shown that a simple mean-field dynamo model with a spherically symmetric helical turbulence parameter…

Third order spectral branch points in Krein space related setups: PT-symmetric matrix toy model, MHD alpha^2-dynamo, and extended Squire equation
Uwe Guenther, Frank Stefani
The spectra of self-adjoint operators in Krein spaces are known to possess real sectors as well as sectors of pair-wise complex conjugate eigenvalues. Transitions from one spectral…

Target mass number dependence of subthreshold antiproton production in proton-, deuteron- and alpha-particle-induced reactions
H. Mueller, V. I. Komarov
Data from KEK on subthreshold $\bar{\mrm{p}}$ as well as on and $\mrm{K}^\pm$ production in proton-, deuteron- and -induced reactions at energies between 2.0 and 12.0 A…
