Topological phase diagrams of the frustrated Ising ferromagnet
Alejandro Mendoza-Coto, Danilo Emanuel Barreto de Oliveira, Lucas Nicolao +1
The emergence of complex modulated structures in the magnetization pattern of thin films is a well-established experimental phenomenology caused by the frustrating effects of compe…
Critical states in Political Trends. How much reliable is a poll on Twitter? A study by means of the Potts Model
Lucas Nicolao, Massimo Ostilli
In recent years, Twitter data related to political trends have tentatively been used to make predictions (poll) about several electoral events. Given candidates for an election…
On the mechanism behind the inverse melting in systems with competing interactions
Alejandro Mendoza-Coto, Lucas Nicolao, Rogelio Díaz-Méndez
Here we present a fundamental comprehension of the microscopic mechanisms leading to the emergence of inverse melting transitions by considering a thorough mean-field analysis of a…
Phase diagram and metastability of the Ising model on two coupled networks
Maíra Bolfe, Lucas Nicolao, Fernando L. Metz
We explore the cooperative behaviour and phase transitions of interacting networks by studying a simplified model consisting of Ising spins placed on the nodes of two coupled Erdös…
Nature of Long-Range Order in Stripe-Forming Systems with Long-Range Repulsive Interactions
Alejandro Mendoza-Coto, Daniel A. Stariolo, Lucas Nicolao
We study two dimensional stripe forming systems with competing repulsive interactions decaying as . We derive an effective Hamiltonian with a short range part and a general…
Symmetry breaking in frustrated systems: effective fluctuation spectrum due to coupling effects
Alejandro Mendoza-Coto, Rogelio Díaz-Méndez, Roberto Mulet +2
We study the Langevin dynamics of a d-dimensional Ginzburg-Landau Hamiltonian with isotropic long range repulsive interactions. We show that, once the symmetry is broken, there is…
