We have considered a numerical scheme for the calculation of the equilibrium properties of spin-12 XY chains. Within its frames it is necessary to solve in the last resort only the 2N × 2N eigenvalue and eigenvector problem but not the 2 × 2 one as for an arbitrary system consisting of N spins 1 2 . To illustrate the approach we have presented some new results. Namely, the xx dynamic structure ...
متن کاملNumerical Approach for the Study of the Spin-1/2 XY Chains Dynamic Properties
The paper presents a numerical approach for the calculation of thermodynamics and spin correlations for spin-2 XY chains. To illustrate the approach we performed exact finite-chain calculations of all time-dependent two-spin correlation functions for the spin-2 Ising chain in the transverse field. The computed correlation functions permit to evaluate the frequency-dependent susceptibilities and...
متن کاملQuantum communication through anisotropic Heisenberg XY spin chains
We study quantum communication through an anisotropic Heisenberg XY chain in a transverse magnetic field. We find that for some time t and anisotropy parameter γ, one can transfer a state with a relatively high fidelity. In the strong-field regime, the anisotropy does not significantly affect the fidelity while in the weak-field regime the affect is quite pronounced. The most interesting case i...
متن کاملA solvable model of a random spin-12 XY chain
The paper presents exact calculations of thermodynamic quantities for the spin2 isotropic XY chain with random lorentzian intersite interaction and transverse field that depends linearly on the surrounding intersite interactions. PACS codes: 75.10.-b
