Query: Energy trapped Ising model   In this paper we have considered the 3D Ising model perturbed with the energy
operator coupled with a non uniform harmonic potential acting as a trap,
showing that this system satisfies the trap-size scaling behavior. Eventually,
we have computed the correlators $\langle \sigma (z) \sigma (0)\rangle$, $
\langle \epsilon (z) \epsilon (0)\rangle$ and $\langle \sigma (z) \epsilon
(0)\rangle$ near the critical point by means of conformal perturbation theory.
Combining this result with Monte Carlo simulations, we have been able to
estimate the OPE coefficients $C^{\sigma}_{\sigma\epsilon}$,
$C^{\epsilon}_{\sigma\sigma}$ and $C^{\epsilon}_{\epsilon\epsilon}$, finding a
good agreement with the values obtained in [1,2].
