International audienceA first-principles investigation of E′ centers in vitreous silica (v−SiO2) based on calculations of the electron paramagnetic resonance (EPR) parameters is presented. The EPR parameters are obtained by exploiting the gauge including projector augmented wave method as implemented in the quantum-espresso package. First, we analyze the EPR parameters of a large number of Si2 dimers. The g tensor of the Si2 dimers is shown to possess an average rhombic symmetry and larger g principal values with respect to those observed, e.g., for the E′γ center in silica. Furthermore, the g principal values clearly show a linear trend with the Si-Si dimer length. Our results suggest that the Si2 dimers could correspond to an unidentified...
