Pinning effects in a two-dimensional cluster glass
Wenlong Wang, Rogelio Díaz-Méndez, Mats Wallin +2
We study numerically the glass formation and depinning transition of a system of two-dimensional cluster-forming monodisperse particles in presence of pinning disorder. The pairwis…
Ultrasoft classical systems at zero temperature
Matheus de Mello, Rogelio Díaz-Méndez, Alejandro Mendoza-Coto
At low temperatures ultrasoft particle systems develop interesting phases via the self-assembly of particle clusters. In this study we develop a general zero-temperature analysis f…
Ground state phase diagram of ultrasoft bosons
Alejandro Mendoza-Coto, Diogo de Souza Caetano, Rogelio Díaz-Méndez
In 2D bosonic systems ultra-soft interactions develop an interesting phenomenology that ultimately leads to the appearance of supersolid phases in free space conditions. While sugg…
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…
Solving the one-dimensional Ising chain via mathematical induction: An intuitive approach to the transfer matrix
Wenlong Wang, Rogelio Díaz-Méndez, Raudys Capdevila
The aim of this work is to present a formulation to solve the one-dimensional Ising model using the elementary technique of mathematical induction. This formulation is physically c…
Scaling of the magnetic permeability at the Berezinskii-Kosterlitz-Thouless transition from Coulomb gas simulations
Rogelio Díaz-Méndez, Jack Lidmar, Mats Wallin
A new approach to the Berezinskii-Kosterlitz-Thouless transition in the two-dimensional Coulomb gas model is explored by MC simulation and finite size scaling. The usual mapping of…
Event-Driven Monte Carlo: exact dynamics at all time-scales for discrete-variable models
Alejandro Mendoza-Coto, Rogelio Díaz-Méndez, Guido Pupillo
We present an algorithm for the simulation of the exact real-time dynamics of classical many-body systems with discrete energy levels. In the same spirit of kinetic Monte Carlo met…
Non-Arrhenius relaxation of the Heisenberg model with dipolar and anisotropic interactions
Rogelio Díaz-Méndez, Roberto Mulet
The dynamical properties of a 2D Heisenberg model with dipolar interactions and perpendicular anisotropy are studied using Monte Carlo simulations in two different ordered regions…
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…
The frustrated spherical model: an alternative to Ginzburg-Landau Hamiltonians with competing interactions
Alejandro Mendoza-Coto, Rogelio Díaz-Méndez
We solve analytically the Langevin dynamics of the classic spherical model considering the ferromagnetic exchange and a long-range antiferromagnetic interaction. Our results in the…
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…
