Chemical systems - molecules, clusters, crystals, glasses, etc. - possess highly complex potential energy surfaces, which control their structural dynamics - aging, folding, relaxation, transformation, etc. First, fundamental concepts of energy landscapes such as locally ergodic regions[1,2] and free energy landscapes[3] will be discussed[4]. In the second part of the talk, we present examples drawn from prediction of crystalline compounds and phase diagrams[2,5], aging in amorphous materials[6], and structure prediction of quasi-two-dimensional systems, clusters[7] and molecules[4].
