Linear response in aging glassy systems, intermittency and the Poisson statistics of record fluctuations

Sibani, P. - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 4, pp. 483-491

We study the intermittent behavior of the energy decay and the linear magnetic response of a glassy system during isothermal aging after a deep thermal quench, using the Edward-Anderson spin glass model as a paradigmatic example. The large intermittent changes in the two observables occur in a...

Pulse trains propagating through excitable media subjected to external noise

Beato, V.; Engel, H.; Schimansky-Geier, L. - In: The European Physical Journal B - Condensed Matter and … 58 (2007) 3, pp. 323-329

We study the propagation of periodic pulse trains in excitable media exposed to external spatio-temporal noise using … weak noise approximation we find noise-induced transitions in the dispersion relation of pulse trains. We discuss noise …-enhanced propagation of pulse trains within a certain wave-length range caused by external noise of moderate strength. Copyright EDP …

Can a few fanatics influence the opinion of a large segment of a society?

Stauffer, D.; Sahimi, M. - In: The European Physical Journal B - Condensed Matter and … 57 (2007) 2, pp. 147-152

Models that provide insight into how extreme positions regarding any social phenomenon may spread in a society or at the global scale are of great current interest. A realistic model must account for the fact that globalization, internet, and other means of mass communications have given rise to...

Quantum Brownian motion and the second law of thermodynamics

Kim, ILki; Mahler, Günter - In: The European Physical Journal B - Condensed Matter and … 54 (2006) 3, pp. 405-414

We consider a single harmonic oscillator coupled to a bath at zero temperature. As is well-known, the oscillator then has a higher average energy than that given by its ground state. Here we show analytically that for a damping model with arbitrarily discrete distribution of bath modes and...

The second law of thermodynamics in the quantum Brownian oscillator at an arbitrary temperature

Kim, I.; Mahler, G. - In: The European Physical Journal B - Condensed Matter and … 60 (2007) 3, pp. 401-408

In the classical limit no work is needed to couple a system to a bath with sufficiently weak coupling strength (or with arbitrarily finite coupling strength for a linear system) at the same temperature. In the quantum domain this may be expected to change due to system-bath entanglement. Here we...
