Global exploration of phase behavior in frustrated Ising models using unsupervised learning techniques
Danilo Rodrigues de Assis Elias, Enzo Granato, Maurice de Koning
We apply a set of machine-learning (ML) techniques for the global exploration of the phase diagrams of two frustrated 2D Ising models with competing interactions. Based on raw Mont…
Zero-temperature transition and correlation-length exponent of the frustrated XY model on a honeycomb lattice
Enzo Granato
Phase coherence and vortex order in the fully frustrated XY model on a two-dimensional honeycomb lattice are studied by extensive Monte Carlo simulations using the parallel temperi…
Glassy phases and driven response of the phase-field-crystal model with random pinning
E. Granato, J. A. P. Ramos, C. V. Achim +4
We study the structural correlations and the nonlinear response to a driving force of a two-dimensional phase-field-crystal model with random pinning. The model provides an effecti…
Pattern Selection in a Phase Field Model for Directional Solidification
R. N. Costa Filho, J. M. Kosterlitz, Enzo Granato
A symmetric phase field model is used to study wavelength selection in two dimensions. We study the problem in a finite system using a two-pronged approach. First we construct an a…
Transverse thermal depinning and nonlinear sliding friction of an adsorbed monolayer
Enzo Granato, S. C. Ying
We study the response of an adsorbed monolayer under a driving force as a model of sliding friction phenomena between two crystalline surfaces with a boundary lubrication layer. Us…
Dynamics near the Surface Reconstruction of W(100)
M. R. Baldan, E. Granato, S. C. Ying
Using Brownian molecular dynamics simulation, we study the surface dynamics near the reconstruction transition of W(100) via a model Hamiltonian. Results for the softening and broa…
Nonlinear response scaling of the two-dimensional XY spin glass in the Coulomb-gas representation
Enzo Granato
Vortex critical dynamics of the two dimensional XY spin glass is studied by Monte Carlo methods in the Coulomb-gas representation. A scaling analysis of the nonlinear response is u…
Dynamical transitions and sliding friction in the two-dimensional Frenkel-Kontorova model
Enzo Granato, S. C. Ying
The nonlinear response of an adsorbed layer on a periodic substrate to an external force is studied via a two dimensional uniaxial Frenkel-Kontorova model. The nonequlibrium proper…
Phase transitions in a frustrated XY model with zig-zag couplings
M. Benakli, E. Granato
We study a new generalized version of the square-lattice frustrated XY model where unequal ferromagnetic and antiferromagnetic couplings are arranged in a zig-zag pattern. The rati…
