Persistence Probabilities of the German DAX and Shanghai Index
F. Ren, B. Zheng, H. Lin +2
We present a relatively detailed analysis of the persistence probability distributions in financial dynamics. Compared with the auto-correlation function, the persistence probabili…
Influence of layer defects on the damping in ferroelectric thin films
J. M. Wesselinowa, T. Michael, S. Trimper +1
A Green's function technique for a modified Ising model in a transverse field is applied, which allows to calculate the damping of the elementary excitations and the phase transiti…
Network of social groups or Let's have a party
Marian Brandau, Steffen Trimper
We present a simple model for growing up and depletion of parties due to the permanent communication between the participants of the events. Because of the rapid exchange of inform…
Critical aging of a ferromagnetic system from a completely ordered state
Andrei A. Fedorenko, Steffen Trimper
We adapt the non-linear model to study the nonequilibrium critical dynamics of O(n) symmetric ferromagnetic system. Using the renormalization group analysis in dimensio…
