    "abstract": "We examine the effects of intra-environmental coupling on decoherence by\nconstructing a low temperature spin--spin-bath model of an atomic impurity in a\nDebye crystal. The impurity interacts with phonons of the crystal through\nanti-ferromagnetic spin-spin interactions. The reduced density matrix of the\ncentral spin representing the impurity is calculated by dynamically integrating\nthe full Schroedinger equation for the spin--spin-bath model for different\nthermally weighted eigenstates of the spin-bath. Exact numerical results show\nthat increasing the intra-environmental coupling results in suppression of\ndecoherence. This effect could play an important role in the construction of\nsolid state quantum devices such as quantum computers.",
