Simulating the spin wave behavior in a spin wave majority gate is a very challenging task, due to its complex shape, multitude of interactions between different materials and the magnetic finite temperature excitations. Nevertheless, studying the ferromagnet at zero temperature using a simple geometry can provide already many of the desired insights. More specifically, the ferromagnet can be described as a saturated spin lattice with a Heisenberg spin Hamiltonian. Displacing some spins from their equilibrium orientation initiates a spin wave, whose dynamics is described using the Heisenberg equation of motion. The geometry itself can range from a finite spin chain up to an infinite two-dimensional lattice.
This project will involve both analytical and numerical calculations in the domains of quantum mechanics and magnetism.
