Abstract
By analyzing spin-spin correlation functions at relatively short distances,we showthat equilibrium near-critical
properties can be extracted at short times after quenches into the vicinity of a quantum critical point. The time
scales after which equilibrium properties can be extracted are sufficiently short so that the proposed scheme
should be viable for quantum simulators of spin models based on ultracold atoms or trapped ions. Our results,
analytic as well as numeric, are for one-dimensional spin models, either integrable or nonintegrable, but we
expect our conclusions to be valid in higher dimensions as well.
