Short-wavelength mesophases in the ground states of core-softened particles in two-dimensions
Rômulo Cenci, Lucas Nicolao, Alejandro Mendoza-Coto
We describe the formation of short-wavelength mesophases in a two-dimensional core-softened particle system. By proposing a series of specific ansatz for each relevant phase, we pe…
Melting of the two-dimensional solid phase in the Gaussian-core model
Alejandro Mendoza-Coto, Valéria Mattiello, Rômulo Cenci +2
A general theory for the melting of two dimensional solids explaining the universal and non-universal properties is an open problem up to date. Although the celebrated KTHNY theory…
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…
Spatial correlation functions and dynamical exponents in very large samples of 4D spin glasses
Lucas Nicolao, Giorgio Parisi, Federico Ricci-Tersenghi
The study of the low temperature phase of spin glass models by means of Monte Carlo simulations is a challenging task, because of the very slow dynamics and the severe finite size…
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…
Dynamics of systems with isotropic competing interactions in an external field: a Langevin approach
Rogelio Díaz-Méndez, Alejandro Mendoza-Coto, Roberto Mulet +2
We study the Langevin dynamics of a ferromagnetic Ginzburg-Landau Hamiltonian with a competing long-range repulsive term in the presence of an external magnetic field. The model is…
Langevin simulations of a model for ultrathin magnetic films
Lucas Nicolao, Daniel A. Stariolo
We show results from simulations of the Langevin dynamics of a two-dimensional scalar model with competing interactions for ultrathin magnetic films. We find a phase transition fro…
