Abstract

Using a multiple integral representation for the correlation functions, we compute the emptiness formation probability of the XXZ spin-½ Heisenberg chain at anisotropy Δ = ½. We prove that it is expressed in terms of the number of alternating sign matrices.

CORRELATION FUNCTIONS OF THE XXZ SPIN-½ HEISENBERG CHAIN: RECENT ADVANCES (REVIEW)

N Kitanine, Jean Michel Maillet, N. A. Slavnov +1 more

We review some recent advances in the computation of exact correlation functions of the XXZ-½ Heisenberg chain. We first give a general introduction to our method which is based on the algebraic Bethe ansatz and the resolution of the quantum inverse scattering problem, leading in particular to multiple integral representations for the correlation functions. Then we describe recently obtained compact formulas for the spin-spin correlation functions of the XXZ-½ Heisenberg chain. We outline how this leads to several explicit results including the known two point functions in the limit of free fermions, the so-called emptiness formation probability at anisotropy Δ=1/2 and its large distance asymptotic behaviour in the massless phase of the model.

Asymptotic Behavior of the Emptiness Formation Probability in the Critical Phase of XXZ Spin Chain

V. E. Korepin, C.N. Yang, Sergei L. Lukyanov +2 more

We study the Emptiness Formation Probability (EFP) for the spin 1/2 XXZ spin chain. EFP P (n) detects a formation of ferromagnetic string of the length n in the ground state. It is expected that EFP decays in a Gaussian way for large strings P (n) n . Here, we propose the explicit expressions for the rate of Gaussian decay C as well as for the exponent . In order to con rm the validity of our formulae, we employed an ab initio simulation technique of the density-matrix renormalization group to simulate XXZ spin chain of sucient length. Furthermore, we performed Monte-Carlo integration of the Jimbo-Miwa multiple integral for P (n). Those numerical results for P (n) support our formulae fairly de nitely.

Finite size emptiness formation probability of the XXZ spin chain at $\Delta =-\frac{1}{2}$

Luigi Cantini A

In this paper, we compute the emptiness formation probability of a (twisted-) periodic XXZ spin chain of finite length at , thus proving the formulas conjectured by Razumov and Stroganov (2001 J. Phys. A: Math. Gen. 34 3185 and 5335–40). The result is obtained by exploiting the fact that the ground state of the inhomogeneous XXZ spin chain at satisfies a set of qKZ equations associated with .

On the emptiness formation probability of the openXXZspin-1/2 chain

Karol Kajetan Kozlowski

This paper is devoted to the study of the emptiness formation probability τ( m ) of the open XXZ chain. We derive a closed form for τ( m ) at Δ = 1/2 when the boundary field vanishes. Moreover we obtain its leading asymptotics for an arbitrary boundary field at the free fermion point. Finally, we compute the first term of the asymptotics of ln(τ( m )) for the whole massless regime −1<Δ<1.

Correlation functions of the integrable higher-spin XXX and XXZ spin chains through the fusion method

Tetsuo Deguchi, Chihiro Matsui

For the integrable higher-spin XXX and XXZ spin chains we present multiple-integral representations for the correlation function of an arbitrary product of Hermitian elementary matrices in the massless ground state. We give a formula expressing it by a single term of multiple integrals. In particular, we explicitly derive the emptiness formation probability (EFP). We assume 2s-strings for the ground-state solution of the Bethe-ansatz equations for the spin-s XXZ chain, and solve the integral equations for the spin-s Gaudin matrix. In terms of the XXZ coupling Δ we define ζ by Δ=cosζ, and put it in a region 0⩽ζ<π/2s of the gapless regime: −1<Δ⩽1 (0⩽ζ<π), where Δ=1 (ζ=0) corresponds to the antiferromagnetic point. We calculate the zero-temperature correlation functions by the algebraic Bethe-ansatz, introducing the Hermitian elementary matrices in the massless regime, and taking advantage of the fusion construction of the R-matrix of the higher-spin representations of the affine quantum group.
