A comparative review of recent results on supercritical anomalies in two-dimensional kinetic Ising and Blume-Capel ferromagnets
Gloria M. Buendía, Celeste Mendes, Per Arne Rikvold
Following the unexpected experimental discovery of ``sideband'' peaks in the fluctuation spectrum of thin Co films driven by a slowly oscillating magnetic field with a constant bia…
Mixed-wet percolation on a dual square lattice
Jnana Ranjan Das, Santanu Sinha, Alex Hansen +1
We present a percolation model that is inspired by recent works on immiscible two-phase flow in a mixed-wet porous medium made of a mixture of grains with two different wettability…
Numerical Simulation of a Two-Dimensional Blume-Capel Ferromagnet in an Oscillating Magnetic Field with a Constant Bias
Celeste Mendes, Gloria M. Buendia, Per Arne Rikvold
We perform a numerical study of the kinetic Blume-Capel (BC) model to find if it exhibits the metamagnetic anomalies previously observed in the kinetic Ising model for supercritica…
Multicritical Bifurcation and First-order Phase Transitions in a Three-dimensional Blume-Capel Antiferromagnet
Daniel Silva, Gloria M. Buendia, Per Arne Rikvold
We present a detailed study by Monte Carlo simulations and finite-size scaling analysis of the phase diagram and ordered bulk phases for the three-dimensional Blume-Capel antiferro…
Modeling crack propagation in heterogeneous materials: Griffith's law, intrinsic crack resistance and avalanches
Subhadeep Roy, Takahiro Hatano, Purusattam Ray
Various kinds of heterogeneity in solids including atomistic discreteness affect the fracture strength as well as the failure dynamics remarkably. Here we study the effects of an i…
Correlation between avalanches and emitted energies during fracture with variable stress release range
Narendra K. Bodaballa, Soumyajyoti Biswas, Subhadeep Roy
We observe the failure process of a fiber bundle model with a variable stress release range, , higher the value of lower the stress release range. By tuning from low to…
