Complexity in Strongly Correlated Electronic Systems

@article{citeulike:2759277, abstract = {A wide variety of experimental results and theoretical investigations in recent years have convincingly demonstrated that several transition metal oxides and other materials have dominant states that are not spatially homogeneous.
