    New Algorithm of the Finite Lattice Method for the High-temperature Expansion of the Ising Model in Three Dimensions

    Full text link
    We propose a new algorithm of the finite lattice method to generate the high-temperature series for the Ising model in three dimensions. It enables us to extend the series for the free energy of the simple cubic lattice from the previous series of 26th order to 46th order in the inverse temperature. The obtained series give the estimate of the critical exponent for the specific heat in high precision.Comment: 4 pages, 4 figures, submitted to Phys. Rev. Letter

    We have calculated the low-temperature series for the second moment of the correlation function in d=3d=3 Ising model to order u26u^{26} and for the free energy of Absolute Value Solid-on-Solid (ASOS) model to order u23u^{23}, using the finite-lattice method.Comment: 3pages, latex, no figures, talk given at LATTICE'94, to appear in the proceeding

    Higher orders of the high-temperature expansion for the Ising model in three dimensions

    Full text link
    The new algorithm of the finite lattice method is applied to generate the high-temperature expansion series of the simple cubic Ising model to β50\beta^{50} for the free energy, to β32\beta^{32} for the magnetic susceptibility and to β29\beta^{29} for the second moment correlation length. The series are analyzed to give the precise value of the critical point and the critical exponents of the model.Comment: Lattice2003(Higgs), 3 pages, 2 figure

    New algorithm of the high-temperature expansion for the Ising model in three dimensions

    Full text link
    New algorithm of the finite lattice method is presented to generate the high-temperature expansion series of the Ising model. It enables us to obtain much longer series in three dimensions when compared not only to the previous algorithm of the finite lattice method but also to the standard graphical method. It is applied to extend the high-temperature series of the simple cubic Ising model from beta^{26} to beta^{46} for the free energy and from beta^{25} to beta^{32} for the magnetic susceptibility.Comment: 3 pages, Lattice2002(spin

    Low-Temperature Series for the Correlation Length in d=3d=3 Ising Model

    Get PDF
    We extend low-temperature series for the second moment of the correlation function in d=3d=3 simple-cubic Ising model from u15u^{15} to u26u^{26} using finite-lattice method, and combining with the series for the susceptibility we obtain the low-temperature series for the second-moment correlation length to u23u^{23}. An analysis of the obtained series by inhomogeneous differential approximants gives critical exponents 2ν+γ2.55 2\nu^{\prime} + \gamma^{\prime} \approx 2.55 and 2ν1.27 2\nu^{\prime} \approx 1.27 .Comment: 13 pages + 5 uuencoded epsf figures in Latex, OPCT-94-

    Large-qq expansion of the specific heat for the two-dimensional qq-state Potts model

    Get PDF
    We have calculated the large-qq expansion for the specific heat at the phase transition point in the two-dimensional qq-state Potts model to the 23rd order in 1/q1/\sqrt{q} using the finite lattice method. The obtained series allows us to give highly convergent estimates of the specific heat for q>4q>4 on the first order transition point. The result confirm us the correctness of the conjecture by Bhattacharya et al. on the asymptotic behavior of the specific heat for q4+q \to 4_+.Comment: 7 pages, LaTeX, 2 postscript figure

    Large-q expansion of the energy and magnetization cumulants for the two-dimensional q-state Potts model

    Get PDF
    We have calculated the large-q expansion for the energy cumulants and the magnetization cumulants at the phase transition point in the two-dimensional q-state Potts model to the 21st or 23rd order in 1/q1/\sqrt{q} using the finite lattice method. The obtained series allow us to give very precise estimates of the cumulants for q>4q>4 on the first order transition point. The result confirms us the correctness of the conjecture by Bhattacharya et al. on the asymptotic behavior not only of the energy cumulants but also of the magnetization cumulants for q4+q \to 4_+.Comment: 36 pages, LaTeX, 20 postscript figures, to appear in Nuclear Physics
