The universal anomalous vibrational and thermal properties of amorphoussolids are believed to be related to the local variations of the elasticity.Recently it has been shown that the vibrational properties are sensitive to theglass's stability. Here we study the stability dependence of the local elasticconstants of a simulated glass former over a broad range of stabilities, from apoorly annealed glass to a glass whose stability is comparable to laboratoryexceptionally stable vapor deposited glasses. We show that with increasingstability the glass becomes more uniform as evidenced by a smaller variance oflocal elastic constants. We find that, according to the definition of localelastic moduli used in this work, the local elastic moduli are not spatiallycorrelated.
