The identification of two-dimensional van der Waals ferromagnetic materials has significantly expanded the realm of magnetic materials and enabled innovative control techniques such as gating and stacking. The dynamical behavior of magnetization is p

A random planar quadrangulation process is introduced as an approximation for certain cellular automata describing neuronal dynamics. This model turns out to be a particular (rectangular) case of a well-known Gilbert tessellation. The central and sti

The Gilbert damping parameter, which describes magnetization dynamics, is crucial for the performance of modern spintronic devices, affecting factors such as the switching speed and critical current density of magnetoresistive random access memory. T

The problem of obtaining spectral densities from lattice data has been receiving great attention due to its importance in our understanding of scattering processes in Quantum Field Theory, with applications both in the Standard Model and beyond. The

We investigated the Gilbert damping in La$_{0.7}$Sr$_{0.3}$MnO$_3$ (LSMO) and La$_{0.7}$Sr$_{0.3}$MnO$_3$/Pt (LSMO/Pt) heterostructures using first-principles calculations and Wannier interpolation techniques. Our work is motivated by recent experime

Spin currents act on ferromagnets by exerting a torque on the magnetisation. This torque is modelled by appending additional terms to the Landau-Lifshitz-Gilbert equation motivating the study of the non-homogeneous Landau-Lifshitz-Gilbert equation. W

Charge-spin interconversion processes underpin the generation of spin-orbit torques in magnetic/nonmagnetic bilayers. However, efficient sources of spin currents such as 5d metals are also efficient spin sinks, resulting in a large increase of magnet

The effect of thermal surface cleaning on the Gilbert damping, $\alpha$, of yttrium iron garnet (YIG), before capping with a metallic layer, has been investigated. Our results show that $\alpha$ is strongly effected by relatively mild annealing condi

Magnetic systems can exhibit thermally activated transitions whose timescales are often described by an Arrhenius law. However, robust predictions of such timescales are only available for certain cases. Inspired by the harmonic theory of Langer, we

The Gilbert--Varshamov (GV) bound is a classical existential result in coding theory. It implies that a random linear binary code of rate $\epsilon^2$ has relative distance at least $\frac{1}{2} - O(\epsilon)$ with high probability. However, it is a
