The context is the Fick law where a stationary current flows in a system
driven by the boundaries in contact with suitable reservoirs. This is a
much studied problem but only recently we have obtained results in models
with phase transition. I will present these models where the stationary non
equilibrium state is known explicitly and exploit this to study the
stationary fluctuations of the interface in the SOS approximation. Beyond
the SOS approximation new interesting and surprising phenomena appear, I
will discuss some preliminary results obtained with Ioffe, Merola, Presutti
and Sholsman.
