A Monte Carlo (spin exchange) method is used to study a spin-1 Ising (lattice-gas) model appropriate for ternary graphite intercalation compounds. In this ... ZX Cai,SD Mahanti - 《Phys Rev B Condens Matter》 被引量: 25发表: 1987年 Staging Transitions in Graphite Intercalation Compounds St...
The Suzuki-Trotter formula has been used to get the m th approximant to the classical representation of the partition function of the N-spin S=12 XY chain. The equivalent two-dimensional (N×2m) Ising model with four-spin interactions has been studied in detail by use of the numerically ex...
Results are presented for the geometry of low-energy excitations in theone-dimensional Ising spin chain with power-law interactions, in which themodel para... HG Katzgraber,AP Young - 《Physical Review B》 被引量: 71发表: 2003年 Spin glass and semiconducting behavior in one-dimensional BaFe2...

We study the fidelity susceptibility in an antiferromagnetic spin-1 XXZ chain numerically. By using the density-matrix renormalization group method, the effects of the alternating single-site anisotropy D on fidelity susceptibility are investigated. Its relation with the quantum phase transition is analy...
We consider the q-state Potts model in one dimension for the cases q=2m, m=1,2,3,. . . . The dynamical critical exponent is calculated with use of the real-space renormalization-group method. We find z=2 in the 4- and 8-state models, which agrees with the Ising case, and specul...
