A method that reveals the multi-level ultrametric tree hidden in p-spin glass like systems

Autor: R. Baviera, Miguel Angel Virasoro

In the study of disordered models like spin glasses the key object of interest is the rugged energy hypersurface defined in configuration space. The statistical mechanics calculation of the Gibbs–Boltzmann partition function gives the information n

Abdus Salam: The passionate, compassionate man and, his masterpiece, the ICTP

Autor: Miguel Angel Virasoro

Publikováno v: International Journal of Modern Physics A. 32:1741002

Abdus Salam was a great man in more than one dimension. The conception and building of the ICTP system required much more than the intelligence of a great scientist. I will stress those other facets that made him such a unique personality: the optimi

Saddle points stability in the replica approach off equilibrium

Autor: Marco E. Ferrero, Miguel Angel Virasoro

Publikováno v: Journal de Physique I. 4:1819-1827

We study the replica free energy surface for a spin glass model near the glassy temperature. In this model the simplicity of the equilibrium solution hides non trivial metastable saddle points. By means of the stability analysis performed for one and

Barriers and metastable states as saddle points in the replica approach

Autor: Jorge Kurchan, Miguel Angel Virasoro, Giorgio Parisi

Publikováno v: Journal de Physique I. 3:1819-1838

In the context of the p-spin spherical model we show how saddle points of the n - 0 replica free energy surface can be interpreted as metastable states or barriers.

Free-Energy Cost for Ultrametricity Violations in Spin Glasses

Autor: Silvio Franz, Miguel Angel Virasoro, Giorgio Parisi

Publikováno v: Europhysics Letters (EPL). 22:405-411

We apply the technique introduced in a previous paper, to study the violation of ultrametricity in a Spin Glass model. We consider 3 real replicas of a Spin Glass near the glassy temperature, constrained in such a way that their overlaps violate ultr

Replica Method and Finite Volume Corrections

Autor: Giorgio Parisi, Miguel Angel Virasoro, Matteo Campellone

In this note we introduce a method to calculate the finite volume corrections to the mean field results for the free energy when replica symmetry is broken at one-step. We find that the naive results are modified by the presence of additional correct
