Decoherence in Quantum Spin Systemsin systems over extended periods of time. We use exact diagonalization, the Chebyshev polynomial technique, four Suzuki-formula algorithms, and the shortiterative-Lanczos method to solve a simple model for decoherence of a quantum spin system by an environment consisting of quantum spins, and compar

Quantum Computing Simulation using the Auxiliary Field Decompositionscribed by . quantum bits is vector in the Kronecker product space. The dimension is the same as the space spanned by the same number of classical bits. but the intention is to sample the problem via a quantum mechanical wave-function “quantum parallel”. To allow the representation of the gates of a

Quenched Disorder Distributions in Three-Dimensional Diluted Ferromagnetsll dilutions the rather strong first-order phase transition of the pure system is found to persist, whereas for larger dilutions the theoretically expected softening to a continuous transition is confirmed. The properties of the underlying disorder distributions of thermal observables are discussed

Critical Exponents of the Two Dimensional Meltingition is now often called as “Alder transition”. They reported that the transition is the first order, but Halperin, Nelson and Young proposed an alternative melting scenario which is based on the Kosterlitz-Thouless (KT) transition. This theory is referred to the Kosterlitz-Thouless-Halperi

Numerical Study of Critical Exponents for Kosterlitz-Thouless Transition Systems in continuous spin systems , while the KT phase appears in . models. In this phase, there is no spontaneous magnetization but the correlation length always diverges. Since the correlation length increases exponentially as the temperature approaches the transition point from disordered phase, it

Relation with input-output analysis,response technique and Heisenberg model is analyzed. The relation between the general “inverse susceptibility” approach and “long wavelength” approximation is established. The smallnes parameter is estimated for ferromagnetic transition metals.
