Abstract Several models for materials of much current interest in condensed matter physics have been numerically studied, using unbiased methods, including Monte Carlo simulations and exact treatment of the fermionic trace at finite temperature. It was found that many of these materials share common phenomenological aspects due to the presence of intrinsic inhomogeneities in the form of "clustered states". Some of these states are highly susceptible to external perturbations. The list includes diluted magnetic semiconductors and high temperature superconducting cuprates among others.
