CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA generating function is introduced to determine the probability P(q) of the overlap q in disordered systems via a product of random transfer matrices. In one-dimensional models, the overlap is obtained by the Lyapunov exponent lambda of the product. Replica symmetry breaking at zero temperature corresponds to a discontinuity of the derivative of lambda with respect to an appropriate coupling variable in the replica space. The method is illustrated in a frustrated magnetic model where q not-equal 0.

| Abstract: | A generating function is introduced to determine the probability P(q) of the overlap q in disordered systems via a product of random transfer matrices. In one-dimensional models, the overlap is obtained by the Lyapunov exponent lambda of the product. Replica symmetry breaking at zero temperature corresponds to a discontinuity of the derivative of lambda with respect to an appropriate coupling variable in the replica space. The method is illustrated in a frustrated magnetic model where q not-equal 0. |
