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…
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…
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…
