Elastic systems with correlated disorder: Response to tilt and application to surface growth
We study elastic systems such as interfaces or lattices pinned by correlated quenched disorder considering two different types of correlations: generalized columnar disorder and quenched defects correlated as $\ensuremath{\sim}{x}^{\ensuremath{-}a}$ for large separation $x$. Using functional renormalization group methods, we obtain the critical exponents to two-loop order and calculate the response …
