开链XXZ自旋-$\tf{1}{2}$链的空态形成几率

On the emptiness formation probability of the open XXZ spin-$\tf{1}{2}$ chain

K. K. Kozlowski

摘要:

本文研究开XXZ链的空性形成概率$τ\pa{m}$。当边界场为零时,我们得到了$τ\pa{m}$在$Δ=\tf{1}{2}$的封闭形式。此外,我们还得到了任意边界场在自由费米子点处的导渐近性。最后,我们计算了$\ln\pa{τ\pa{m}}$在整个无质量区$-1<Δ<1$的渐近性的第一项。

英文摘要:

This paper is devoted to the study of the emptiness formation probability $τ\pa{m}$ of the open XXZ chain. We derive a closed form for $τ\pa{m}$ at $Δ=\tf{1}{2}$ 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 $\ln\pa{τ\pa{m}}$ in the whole massless regime $-1<Δ<1$.
