Uniform bound of the entanglement for the ground state of the quantum Ising model with large transverse magnetic field

Massimo Campanino, Michele Gianfelice

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…
