States of Low Energy (SLEs) have been constructed in cosmological spacetimes as the ones that minimize the mode contribution to the regularized energy density. These have been shown to be an adequate choice of vacuum state for primordial perturbations in models that include a period of kinetic domination prior to inflation. This is precisely the case in Loop Quantum Cosmology (LQC). In this talk we will review the construction and properties of SLEs for a general FLRW model and explore their application to LQC.
