    "abstract": "A low temperature model system consisting of a central spin coupled to a\nspin-bath is studied to determine whether interaction among bath spins has an\neffect on central spin dynamics. In the absence of intra-environmental\ncoupling, decoherence of the central spin is fast and irreversible. Strong\nintra-environmental interaction results in an effective decoupling of the\ncentral spin from the bath and suppression of decoherence. Weaker\nintra-environmental coupling reduces but does not eliminate decoherence. We\nbelieve that similar behaviour will be observed in any system with a\nself-interacting environment.",
