In the first part of this thesis, the properties of physical systems in the presence of quenched disorder are studied. The phase diagrams and the statistical mechanics of classical Ising systems that go undergo phase transitions are obtained for the case of a random external field and a random exchange (spin-glass) interaction between spins. Uniting phase diagrams, for the general case of a system that include both spin-glass exchange interaction and the external fields, are obtained via… CONTINUE READING
