There are No Nice Interfaces in 2+1 Dimensional SOS-Models in Random Media
Abstract
We prove that in dimension d≤ 2 translation covariant Gibbs states describing rigid interfaces in a disordered solid-on-solid (SOS) cannot exist for any value of the temperature, in contrast to the situation in d≥ 3. The prove relies on an adaptation of a theorem of Aizenman and Wehr. Keywords: Disordered systems, interfaces, SOS-model
