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

Figure 1

Central electron spin coupled to a one-dimensional anisotropic-antiferromagnetic spin systems. The spin configuration is compatible with the spin state in a sublattice (i.e., the spins on each sublattice are antiparallel). (a) and (b) represent physical configuration of a two-interpenetrating quantum spin systems.
