Spin Wave Decoherence in the Presence of Dispersive Shock Waves

The processes for generation, amplification, and protraction of oscillating signals - often for information transfer - are inherently associated with dispersive decoherence and nonlinear phenomena. One such example are shock waves, which can be generated alongside, or instead of, the desired signal while dispersion and broadening can limit the propagation range of spin waves. Here, we develop a numerical model to investigate a generation process which results in dispersive shockwaves (DSW) being observed. In contrast to previous work, our system is strictly linear and does not require surface spin waves to observe DSW. We demonstrate how decoherence associated to DSWs is an inherent property of signals propagating through spin wave systems. We then discuss use cases for this behaviour.
