Abstract

The purpose of this modest note is to provide a short proof of the sharpness of the phase transition for the Random-cluster model with q=2q=2 by extending the approach developed by Duminil-Copin and Tassion for q=1q=1. This in particular implies the exponential decay of the two point-correlation function in the subcritical Ising model.
