论文摘要
我们考虑具有有限体积\ [λ{_ {m}：= \ { - m，-m+1，\ ldots，m+l \} \。} \。}％\]的量子液体模型的基态状态在一个维度中$ h $在一个维度中\ [λ{_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_ {_} 0，..，l \ right \} $相对于其补充$λ_{m} \backslashλ_{0} $，在$ m $和$ l $中是均匀的。通过合适的群集扩展建立结合。
We consider the ground state of the quantum Ising model with transverse field $h$ in one dimension in a finite volume \[ Λ{_{m}:=\{-m,-m+1,\ldots,m+L\}\ .}% \] For $h$ sufficiently large we prove a bound for the entanglement of the interval $Λ_{0}:=\left\{ 0,..,L\right\} $ relative to its complement $Λ_{m}\backslashΛ_{0}$ which is uniform in $m$ and $L$. The bound is established by means of a suitable cluster expansion.
