We report the first large scale molecular dynamics simulations of the effect of the photoisomerization of probe molecules on the dynamics of a glassy molecular material. We show that the photoisomerization of the probe molecules induces the creation of an artificial dynamical heterogeneity inside the matrix. We then study the modification of the dynamics and find, in agreement with recent experiments, an important increase of the diffusion leading to liquid like diffusion below the glass transition temperature. We find that the photoisomerization process controls the heterogeneity and the non-Gaussian parameter of the material, leading to extremely rapid variations of these quantities.
