Non-minimal monopoles of the Dirac type as realization of the censorship conjecture
Alexander B. Balakin, Heinz Dehnen, Alexei E. Zayats
We discuss a class of exact solutions of a three-parameter non-minimally extended Einstein-Maxwell model, which are attributed to non-minimal magnetic monopoles of the Dirac type.…
A Double-Transition Scenario for Anomalous Diffusion in Glass-Forming Mixtures
Th. Voigtmann, J. Horbach
We study by molecular dynamics computer simulation a binary soft-sphere mixture that shows a pronounced decoupling of the species' long-time dynamics. Anomalous, power-law-like dif…
Width of the phase transition in diffusive magnetic Josephson junctions
Zahra Shomali, Malek Zareyan, Wolfgang Belzig
We investigate the Josephson current between two superconductors (S) which are connected through a diffusive magnetic junction with a complex structure (F). Using the quantum…
Some hints for the design of digital chaos-based cryptosystems: lessons learned from cryptanalysis
David Arroyo, Gonzalo Alvarez, Shujun Li
In this work we comment some conclusions derived from the analysis of recent proposals on the field of chaos-based cryptography. These observations remark the main problems detecte…
Correlation between magnetism and spin-dependent transport in CoFeB alloys
P. V. Paluskar, R. Lavrijsen, M. Sicot +3
We report a correlation between the spin polarization of the tunneling electrons (TSP) and the magnetic moment of amorphous CoFeB alloys. Such a correlation is surprising since the…
Dichotomy Results for Fixed Point Counting in Boolean Dynamical Systems
Christopher M. Homan, Sven Kosub
We present dichotomy theorems regarding the computational complexity of counting fixed points in boolean (discrete) dynamical systems, i.e., finite discrete dynamical systems over…
