Kinetically roughened surfaces lie at the heart of a fascinatingly rich, multidisciplinary branch of nonequilibrium statistical mechanics. Diverse stochastic growth processes can be understood via a noisy Burgers equation due to Kardar, Parisi and Zhang, whose consequences and variations have mobilized a sizeable community of theoretical, numerical and experimental physicists. A Hopf-Cole transformation relates these KPZ surfaces to directed polymers in random media, a baby version of the spin-glass problem, which at zero temperature is a matter of global optimization, concerning extremal paths through a random energy landscape In this talk, we give an account of this intriguing field, concentrating on two main lines - the interface growth equations themselves, and their directed polymer counterparts.
