1) XXZ model XXZ模型1. Thermal entanglement of XXZ model under magnetic field; 磁场作用下XXZ模型的热力学纠缠2. Content: In this paper, the quantum phase transition of the XXZ model of Heisenberg closespin-1/2 chains in one dimension is studied, the nearest neighbor interaction of Fermi...
The XXZ model ( s = 1 2 ) in a transverse field on a double chain with a uniform long-range interaction among the z components of the spins is considered. The nearest-neighbour interactions are restricted to the components in the xy plane and to the spins within the same chain leg, ...
We derive functional equations for the eigenvalues of the XXZ model subject to anti-diagonal twisted boundary conditions by means of fusion of transfer matrices and by Sklyanin's method of separation of variables. Our findings coincide with those obtained using Baxter's method and are compared to...
The transfer matrix T(λ, ν) depends on the anisotropy ν and the spectral parameter λ that fixes the model. (The thermodynamic limit of Tis believed to describe conformal field theory of central charge c = 1 6λ/(π(λ π)).) The family of periodic XXZ Hamiltonians is extended to...

We consider the XXZ model in the infinite volume limit with spin half quantumspace and higher spin auxiliary space. Using perturbation theory arguments, werelate the half infinite transfer matrices of this class of models to certain$U_q(\hat{sl_2})$ intertwiners introduced by Nakayashiki. We...

The correlation functions ρxx(R,t) and ρyy(R,t) are calculated for the one-dimensional Ising model with a transverse field h at T=0. This model corresponds to the XY model with γ=1, and is equivalent to the two-dimensional anisotropic... J Lajzerowicz,P Pfeuty - 《Physical Revie...
We study the fidelity susceptibility in the two-dimensional (2D) transverse-field Ising model and the 2D XXZ model numerically. It is found that in both models, the fidelity susceptibility as a function of the driving parameter diverges at the critical points. The validity of the fidelity susce...
