Critical Exponents for Diluted Resistor Networks
O. Stenull, H. K. Janssen, K. Oerding
An approach by Stephen is used to investigate the critical properties of randomly diluted resistor networks near the percolation threshold by means of renormalized field theory. We…
Equation of state for directed percolation
H. K. Janssen, Ue. Kutbay, K. Oerding
Using field-theoretic renormalization group methods we calculate the equation of state for non-equilibrium systems belonging to the universality class of directed percolation (Grib…
Levy-flight spreading of epidemic processes leading to percolating clusters
H. K. Janssen, K. Oerding, F. van Wijland +1
We consider two stochastic processes, the Gribov process and the general epidemic process, that describe the spreading of an infectious disease. In contrast to the usually assumed…
Surface critical behavior of driven diffusive systems with open boundaries
K. Oerding, H. K. Janssen
Using field theoretic renormalization group methods we study the critical behavior of a driven diffusive system near a boundary perpendicular to the driving force. The boundary act…
Global Persistence in Directed Percolation
Klaus Oerding, Frederic van Wijland
We consider a directed percolation process at its critical point. The probability that the deviation of the global order parameter with respect to its average has not changed its s…
