Geomagnetic reversals at the edge of regularity
Breno Raphaldini, Everton S. Medeiros, David Ciro +2
Geomagnetic field reversals remain as one of the most intriguing problems in geophysics and are regarded as chaotic processes resulting from a dynamo mechanism. In this article, we…

Evidence for crisis-induced intermittency during geomagnetic superchron transitions
Breno Raphaldini, David Ciro, Everton S. Medeiros +2
The geomagnetic field's dipole undergoes polarity reversals in irregular time intervals. Particularly long periods (of the order of yrs) without reversals, named superchrons,…

Real-time vulnerability of synchronized states
Everton S Medeiros, Rene O. Medrano-T, Iberê Luiz Caldas +2
The time-dependent vulnerability of synchronized states is shown for a complex network composed of electronic circuits. We demonstrate that disturbances to the local dynamics of ne…
