Critical thermodynamics of the two-dimensional +/-J Ising spin glass
J. Lukic, A. Galluccio, E. Marinari +2
We compute the exact partition function of 2d Ising spin glasses with binary couplings. In these systems, the ground state is highly degenerate and is separated from the first exci…
Scalings of domain wall energies in two dimensional Ising spin glasses
Carlo Amoruso, Enzo Marinari, Olivier C Martin +1
We study domain wall energies of two dimensional spin glasses. The scaling of these energies depends on the model's distribution of quenched random couplings, falling into three di…
A Quantitative Clustering Approach to Ultrametricity in Spin Glasses
Stefano Ciliberti, Enzo Marinari
We discuss the problem of ultrametricity in mean field spin glasses by means of a hierarchical clustering algorithm. We complement the clustering approach with quantitative testing…
Localization of Denaturation Bubbles in Random DNA Sequences
Terence Hwa, Enzo Marinari, Kim Sneppen +1
We study the thermodynamic and dynamic behaviors of twist-induced denaturation bubbles in a long, stretched random sequence of DNA. The small bubbles associated with weak twist are…
