Abstract
We study the model of a driven interface in a disordered medium including the KPZ-nonlinearity. The coupled functional renormalization
group flow equations for the disorder correlator and the coupling constant associated with the KPZ-nonlinearity possess a
strong coupling fixed-point for the interface dimensions
d=1, 2. In
d=1 we get the roughness exponent and the dynamical exponent in one-loop approximation respectively as
and
z=1.
