Effect of Noise on the Decoherence of a Central Electron Spin Coupled to an Antiferromagnetic Spin Bath

Figure 3

Plot of the dispersion relation versus the wave vector (𝑥=𝑘𝑙). Red curves for the spin branches with frequency 𝜔⁻; blue curve for the spin branches with frequency 𝜔⁺. Both curves show basin-like behavior.
