Existence of LRO in the FrustratedXXZModel on the Square Lattice

Abstract

We extend the proof for the existence of long-range order(LRO) in the frustrated X X Z model with nearest and next nearest neighbor interactions on the square lattice. It is shown that the Néel LRO exists in the frustrated X Y model when frustration is weak.

Existence of Long Range Order in the Frustrated Heisenberg Model

Tatsuya Kishi, Kenn Kubo

The existence of long range order (LRO) is examined in the antiferromagnetic Heisenberg model on the square or the simple cubic lattice with the next nearest neighbor interactions which are taken to be λ times the nearest neighbor ones (λ≧0). It is rigorously shown that Néel LRO exists at a low temperature on the simple cubic lattice and in the ground state on the square lattice for λ smaller than a critical value λ c . On the square lattice λ c increases with S starting from 0.072 for S =1 and approaches 0.5 in the limit S →∞. On the simple cubic lattice λ c =0.002 for S =1/2 and approaches 0.25 in the limit S →∞.

Long-Range Order in the FrustratedXXZModel

Yôhei Saika, Hidetoshi Nishimori

We examine the existence of long-range order in the two-dimensional frustrated X X Z model with next nearest neighbor interactions using the spin wave theory and the method of infrared bounds. The results show that the X Y -like system may have essentially the same properties as the isotropic Heisenberg case, while the Ising-like system is very unlikely to show non-classical behavior. We also prove the absence of twisted order.

Existence of Long-Range Order in the XXZ Model

Kenn Kubo, Tatsuya Kishi

The method of Kennedy, Lieb, and Shastry is applied to the antiferromagnetic $\mathrm{XXZ}$ model to examine the existence of long-range order (LRO). On the 3D simple-cubic lattice LRO is proved to exist for any $S\ensuremath{\geqq}\frac{1}{2}$ and $\ensuremath{\Delta}\ensuremath{\geqq}0$ at low temperature. On the 2D square lattice LRO exists in the ground state for any $\ensuremath{\Delta}\ensuremath{\leqq}0$ if $S\ensuremath{\geqq}1$ and for $0\ensuremath{\leqq}\ensuremath{\Delta}<0.13$ and $\ensuremath{\Delta}=0$ if $S=\frac{1}{2}$. The existence of LRO in the ground state of the $S=\frac{1}{2} \mathrm{XY}$ model ($\ensuremath{\Delta}=0$), therefore, has been confirmed, in agreement with the conjecture by Nishimori et al. The ground state of the $S=\frac{1}{2}$ antiferromagnetic Heisenberg model in two dimensions still remains to be clarified.

Existence of Long-Range Magnetic Order in the Ground State of Two-Dimensional Spin-1/2 Heisenberg Antiferromagnets

Martin Indergand, Manfred Sigrist

We give a rigorous proof of the existence of long-range antiferromagnetic order in the ground state of several two-dimensional spin-1/2 Heisenberg systems.Three types of systems are considered.The first type consists of an even number, N , of coupled square lattices with antiferromagnetic nearest-neighbor Heisenberg interactions.In this case, we prove the existence of long-range order (LRO) in the ground state for an interplane to inplane coupling ratio r in the range 0.16 ≤ r ≤ 2.1 for N ≥ 4. Further, we prove that the antiferromagnetic bilayer with ferromagnetic next-nearest-neighbor (nnn) interplane couplings possesses LRO in the ground state for 0.21 ≤ r < 1/4, where r is the absolute value of the ratio of the ferromagnetic and antiferromagnetic couplings.The final example consists of two antiferromagnetic spin-1/2 square lattices that are coupled via an antiferromagnetic nnn interplane coupling r.For r = 1, this system is effectively a spin-1 square lattice and has an ordered ground state.We show that LRO exists in the region 0.85 ≤ r ≤ 1. * ) Note that E r q in the notation of KLS corresponds to 2 + r -E q in our notation.

Ground-State Long-Range Order in the Two-DimensionalXXZMode

Hidetoshi Nishimori, Yukiyasu Ozeki

We prove the existence of Néel-type long-range order in the ground state of the spin-1/2 XXZ model with Δ (exchange anisotropy)>1.67 on the square lattice. We further show the existence of long-range order for Δ >1.10 and 0≦ Δ <0.59 by assuming monotonicity of nearest neighbor correlations as functions of the system size. The assumption of monotonicity is supported by numerical calculations.

Existence of Long-Range Order in the XY Model

Kenn Kubo

The existence of long-range order (LRO) at low temperature in the isotropic $\mathrm{XY}$ model with spin $S\ensuremath{\geqq}1$ on simple cubic lattice in three or more dimensions is shown. This completes the proof of the existence of LRO at low temperature in the isotropic $\mathrm{XY}$ model with arbitrary spin size in three or more dimensions, as the proof for $S=\frac{1}{2}$ was given earlier by Dyson, Lieb, and Simon. The existence of LRO in the ground state is shown for $S\ensuremath{\geqq}\frac{3}{2}$ in two dimensions.

The method of Kennedy, Lieb, and Shastry is applied to the antiferromagnetic XXZ\mathrm{XXZ}XXZ model to examine the existence of long-range order (LRO). On the 3D simple-cubic lattice LRO is proved to exist for any $S\ensuremath{\geqq}\frac{1}{2}$ and $\ensuremath{\Delta}\ensuremath{\geqq}0$ at low temperature. On the 2D square lattice LRO exists in the ground state for any $\ensuremath{\Delta}\ensuremath{\leqq}0$ if $S\ensuremath{\geqq}1$ and for $0\ensuremath{\leqq}\ensuremath{\Delta}<0.13$ and $\ensuremath{\Delta}=0$ if S=12S=\frac{1}{2}S=21​. The existence of LRO in the ground state of the S=12XYS=\frac{1}{2} \mathrm{XY}S=21​XY model ($\ensuremath{\Delta}=0$), therefore, has been confirmed, in agreement with the conjecture by Nishimori et al. The ground state of the S=12S=\frac{1}{2}S=21​ antiferromagnetic Heisenberg model in two dimensions still remains to be clarified.
