Coalition Structure and Polarization in Parliamentary Voting Networks: Evidence from the Italian Parliament
Francesca Collu, Antonio Scala, Emilia La Nave
Ensuring legislative accountability in multi-party systems requires quantitative tools that reveal actual voting behavior beyond formal party affiliations. We present a network-bas…
Saddle index properties, singular topology, and its relation to thermodynamical singularities for a phi^4 mean field model
D. A. Garanin, R. Schilling, A. Scala
We investigate the potential energy surface of a phi^4 model with infinite range interactions. All stationary points can be uniquely characterized by three real numbers $α_+, alpha…
Quasi-saddles as relevant points of the potential energy surface in the dynamics of supercooled liquids
L. Angelani, R. Di Leonardo, G. Ruocco +2
The supercooled dynamics of a Lennard-Jones model liquid is numerically investigated studying relevant points of the potential energy surface, i.e. the minima of the square gradien…
Off-equilibrium dynamics in the energy landscape of a simple model glass
R. Di Leonardo, L. Angelani, G. Parisi +3
The aging dynamics of a simple model glass is numerically investigated observing how it takes place in the potential energy landscape . Partitioning the landscape in basins of m…
A stroll in the energy landscape
Antonio Scala, Luca Angelani, Roberto Di Leonardo +2
We review recent results on the potential energy landscape (PES) of model liquids. The role of saddle-points in the PES in connecting dynamics to statics is investigated, confirmin…
Thermodynamically Important Contacts in Folding of Model Proteins
Antonio Scala, Nikolay V. Dokholyan, Sergey V. Buldyrev +1
We introduce a quantity, the entropic susceptibility, that measures the thermodynamic importance-for the folding transition-of the contacts between amino acids in model proteins. U…
Thermodynamic and structural aspects of the potential energy surface of simulated water
Francis W. Starr, Srikanth Sastry, Emilia La Nave +3
Relations between the thermodynamics and dynamics of supercooled liquids approaching a glass transition have been proposed over many years. The potential energy surface of model li…
Instantaneous Normal Mode Analysis of Supercooled Water
Emilia La Nave, Antonio Scala, Francis W. Starr +2
We use the instantaneous normal mode approach to provide a description of the local curvature of the potential energy surface of a model for water. We focus on the region of the ph…
