Transport on Directed Percolation Clusters [PDF]

, 2000
We study random lattice networks consisting of resistor like and diode like bonds. For investigating the transport properties of these random resistor diode networks we introduce a field theoretic Hamiltonian amenable to renormalization group analysis ...

Field theory of directed percolation with long-range spreading [PDF]

, 2008
It is well established that the phase transition between survival and extinction in spreading models with short-range interactions is generically associated with the directed percolation (DP) universality class.

Renormalized field theory of collapsing directed randomly branched polymers [PDF]

, 2009
We present a dynamical field theory for directed randomly branched polymers and in particular their collapse transition. We develop a phenomenological model in the form of a stochastic response functional that allows us to address several interesting ...

Burgen auf engem Raum. Aktion und Reaktion im mittelalterlichen Burgenbau und das Problem der Identifikation [PDF]

, 2017
Anhand ausgewählter Beispiele kann aufgezeigt werden, dass zwei in unmittelbarer Nachbarschaft zueinander befindliche Burgen, die auf den ersten Blick dem Phänomen einer ‚Doppelburg‘ entsprechen, aus unterschiedlichen Gründen entstanden sein können ...

On the relevance of percolation theory to the vulcanization transition [PDF]

, 2001
The relationship between vulcanization and percolation is explored from the perspective of renormalized local field theory. We show rigorously that the vulcanization and percolation correlation functions are governed by the same Gell--Mann-Low ...

Anomalous elasticity in nematic and smectic elastomer tubule [PDF]

, 2008
We study anomalous elasticity in the tubule phases of nematic and smectic elastomer membranes, which are flat in one direction and crumpled in another.

First-order phase transitions in outbreaks of co-infectious diseases and the extended general epidemic process

, 2016
In co-infections, positive feedback between multiple diseases can accelerate outbreaks. In a recent letter Chen, Ghanbarnejad, Cai, and Grassberger (CGCG) introduced a spatially homogeneous mean-field model system for such co-infections, and studied this

Distribution functions in percolation problems [PDF]

, 2009
Percolation clusters are random fractals whose geometrical and transport properties can be characterized with the help of probability distribution functions.

Logarithmic Corrections in Dynamic Isotropic Percolation

, 2003
Based on the field theoretic formulation of the general epidemic process we study logarithmic corrections to scaling in dynamic isotropic percolation at the upper critical dimension d=6.
