Coarse-grained models of stripe forming systems : phase diagrams, anomalies, and scaling hypothesis
Mendoza Coto, Alejandro; Stariolo, Daniel Adrian (2012) [Artigo de periódico]Two coarse-grained models which capture some universal characteristics of stripe forming systems are studied. At high temperatures, the structure factors of both models attain their maxima on a circle in reciprocal space, ... -

Competing interactions, the renormalization group, and the isotropic-nematic phase transition
Barci, Daniel G.; Stariolo, Daniel Adrian (2007) [Artigo de periódico]We discuss 2D systems with Ising symmetry and competing interactions at different scales. In the framework of the renormalization group, we study the effect of relevant quartic interactions. In addition to the usual constant ... -
Critical behavior of self-assembled rigid rods on two-dimensional lattices : Bethe-Peierls approximation and Monte Carlo simulations
López, Luis G.; Linares, Daniel Humberto; Ramírez Pastor, Antonio José; Stariolo, Daniel Adrian; Cannas, Sergio A. (2013) [Artigo de periódico]The critical behavior of adsorbed monomers that reversibly polymerize into linear chains with restricted orientations relative to the substrate has been studied.

Distance between inherent structures and the influence of saddles on approaching the mode coupling transition in a simple glass former
Fabricius, Gabriel; Stariolo, Daniel Adrian (2002) [Artigo de periódico]We analyze through molecular dynamics simulations of a Lennard-Jones (LJ) binary mixture the statistics of the distances between inherent structures sampled at temperatures above the mode coupling transition temperature ... -
Dynamics of the frustrated ising lattice gas
Arenzon, Jeferson Jacob; Ricci-Tersenghi, Federico; Stariolo, Daniel Adrian (2000) [Artigo de periódico]The dynamical properties of a three-dimensional model glass, the frustrated Ising lattice gas (FILG), are studied by Monte Carlo simulations. We present results of compression experiments, where the chemical potential is ... -
Energy landscape of the finite-size mean-field 2-spin spherical model and topology trivialization
Mehta, Dhagash; Hauenstein, Jonathan D.; Niemerg, Matthew; Simm, Nicholas J.; Stariolo, Daniel Adrian (2015) [Artigo de periódico]Motivated by the recently observed phenomenon of topology trivialization of potential energy landscapes (PELs) for several statistical mechanics models, we perform a numerical study of the finite-size 2-spin spherical model ... -
Energy landscape of the finite-size spherical three-spin glass model
Mehta, Dhagash; Stariolo, Daniel Adrian; Kastner, Michael (2013) [Artigo de periódico]We study the three-spin spherical model with mean-field interactions and Gaussian random couplings. For moderate system sizes of up to 20 spins, we obtain all stationary points of the energy landscape by means of the ... -
Fickian crossover and length scales from two point functions in supercooled liquids
