Query: Entanglement Entropy in a Non-Conformal Background   We use gauge-gravity duality to compute entanglement entropy in a
non-conformal background with an energy scale $\Lambda$. At zero temperature,
we observe that entanglement entropy decreases by raising $\Lambda$. However,
at finite temperature, we realize that both $\frac{\Lambda}{T}$ and
entanglement entropy rise together. Comparing entanglement entropy of the
non-conformal theory, $S_{A(N)}$, and of its conformal theory at the $UV$
limit, $ S_{A(C)}$, reveals that $S_{A(N)}$ can be larger or smaller than
$S_{A(C)}$, depending on the value of $\frac{\Lambda}{T}$.
