Smectic-$A$ elastomers with weak director anchoring (2008)
Adams, J. M., Warner, M., Stenull, O., Lubensky, T. C.
Experimentally it is possible to manipulate the director in a (chiral) smectic-$A$ elastomer using an electric field. This suggests that the director is not necessarily locked to the layer normal, as...
Master Operators Govern Multifractality in Percolation (2000)
Using renormalization group methods we study multifractality in percolation at the instance of noisy random resistor networks. We introduce the concept of master operators. The multifractal moments...
Diluted Networks of Nonlinear Resistors and Fractal Dimensions of Percolation Clusters (1999)
We study random networks of nonlinear resistors, which obey a generalized Ohm's law, $V\sim I^r$. Our renormalized field theory, which thrives on an interpretation of the involved Feynman Diagrams as...
The Resistance of Feynman Diagrams and the Percolation Backbone Dimension (1999)
Janssen, H. K., Stenull, O., Oerding, K.
We present a new view of Feynman diagrams for the field theory of transport on percolation clusters. The diagrams for random resistor networks are interpreted as being resistor networks themselves....
Critical Exponents for Diluted Resistor Networks (1998)
Stenull, O., Janssen, H. K., Oerding, K.
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 reformulate an...
