Long-range epidemic spreading with immunization
Florian Linder, Johannes Tran-Gia, Silvio R. Dahmen +1
We study the phase transition between survival and extinction in an epidemic process with long-range interactions and immunization. This model can be viewed as the well-known gener…
Stochastic differential equations with time-delayed feedback and multiplicative noise
Silvio R. Dahmen, Haye Hinrichsen
The stochastic differential equation with a time-delayed feedback and a multiplicative Gaussian noise is shown to be related to Kardar-…
Coupling between static friction force and torque for a tripod
Silvio R. Dahmen, Haye Hinrichsen, Andrey Lysov +1
If a body is resting on a flat surface, the maximal static friction force before motion sets in is reduced if an external torque is also applied. The coupling between the static fr…
Local persistense and blocking in the two dimensional Blume-Capel Model
Roberto da Silva, Silvio R. Dahmen
In this letter we study the local persistence of the two--dimensional Blume-- Capel Model by extension of the concept of Glauber dynamics. We verify that for any value of the ratio…
Directed Percolation and the Golden Ratio
Stephan M Dammer, Silvio R Dahmen, Haye Hinrichsen
Applying the theory of Yang-Lee zeros to nonequilibrium critical phenomena, we investigate the properties of a directed bond percolation process for a complex percolation parameter…
A novel exponent in the Equilibrium Shape of Crystals
S. R. Dahmen, B. Wehefritz, G. Albertini
A new exponent characterizing the rounding of crystal facets is found by mapping a crystal surface onto the asymmetric six-vertex model (i.e. with external fields h and v) and usin…
