    "abstract": "Computer simulations of decoherence in quantum spin systems require the\nsolution of the time-dependent Schrodinger equation for interacting quantum\nspin systems over extended periods of time. We use exact diagonalization,\nChebyshev polynomial technique, four Suzuki-formula algorithms, and the\nshort-iterative-Lanczos method to solve a simple model for decoherence of a\nquantum spin system by an environment consisting of quantum spins, and compare\nadvantages and limitations of different algorithms.",
