    "abstract": "This Letter studies the decoherence in a system of two antiferromagnetically\ncoupled spins that interact with a spin bath environment. Systems are\nconsidered that range from the rotationally invariant to highly anisotropic\nspin models, have different topologies and values of parameters that are fixed\nor are allowed to fluctuate randomly. We explore the conditions under which the\ntwo-spin system clearly shows an evolution from the initial spin-up - spin-down\nstate towards the maximally entangled singlet state. We demonstrate that\nfrustration and, especially, glassiness of the spin environment strongly\nenhances the decoherence of the two-spin system.",
