A spin wave is a propagating disturbance in the ordering of a magnetic material. These low-lying collective excitations occur in magnetic lattices with continuous symmetry. From the equivalent quasiparticle point of view, spin waves are known as magnons, which are bosonic modes of the spin lattice that correspond roughly to the phonon excitations of the nuclear lattice. As temperature is increased, the thermal excitation of spin waves reduces a ferromagnet's spontane… WebApr 13, 2024 · The solid red line shows a sine fit to the data. Dashed red and blue lines show the numerical spin evolution with n ¯ = 0.1 and 6, respectively. (b) Average spin excitation of two-ion crystal under the Mølmer-Sørensen interaction. The solid blue line is a fit of a sine function with an exponential decay envelope. Reuse & Permissions
