Classification and sparse-signature extraction from gene-expression data
Andrea Pagnani, Francesca Tria, Martin Weigt
In this work we suggest a statistical mechanics approach to the classification of high-dimensional data according to a binary label. We propose an algorithm whose aim is twofold: F…
Glass transition and random walks on complex energy landscapes
Andrea Baronchelli, Alain Barrat, Romualdo Pastor-Satorras
We present a simple mathematical model of glassy dynamics seen as a random walk in a directed, weighted network of minima taken as a representation of the energy landscape. Our app…
Separability and ground state factorization in quantum spin systems
S. M. Giampaolo, G. Adesso, F. Illuminati
We investigate the existence and the properties of fully separable (fully factorized) ground states in quantum spin systems. Exploiting techniques of quantum information and entang…
Slip line growth as a critical phenomenon
Fabio Leoni, Stefano Zapperi
We study the growth of slip line in a plastically deforming crystal by numerical simulation of a double-ended pile-up model with a dislocation source at one end, and an absorbing w…
Crack Roughness in the 2D Random Threshold Beam Model
Phani K. V. V. Nukala, Stefano Zapperi, Mikko Alava +1
We study the scaling of two-dimensional crack roughness using large scale beam lattice systems. Our results indicate that the crack roughness obtained using beam lattice systems do…
Free energy landscape of mechanically unfolded model proteins: extended Jarzinsky versus inherent structure reconstruction
Stefano Luccioli, Alberto Imparato, Alessandro Torcini
The equilibrium free energy landscape of off-lattice model heteropolymers as a function of an internal coordinate, namely the end-to-end distance, is reconstructed from out-of-equi…
