Abstract

Frustrated materials show an unusual and complex behavior when their huge ground state degeneracy is lifted by external fields, quantum fluctuations, or quenched disorder. I will discuss mechanisms by which disorder can bring together seemingly incompatible states, e.g., magnetism and superconductivity, the coexistence of which was observed in low-dimensional organic materials, high-temperature superconductors, and heavy fermion compounds. I will also show that frustration is an inherent property of the orbital exchange in charge transfer insulators. It plays an important role in determining structural and magnetic properties of these Jahn-Teller materials.
