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…
A simplified pore-scale model for slow drainage including film-flow effects
Paula Reis, Marcel Moura, Gaute Linga +3
Film flow through networks of corners and capillary bridges can establish connections between seemingly isolated clusters during drainage in porous media. Coupled with drainage thr…
A unified field theory of topological defects and non-linear local excitations
Vidar Skogvoll, Jonas Rønning, Marco Salvalaglio +1
Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively descr…
