Using a combination of density functional theory and dynamical-mean-field theory we study the electric polarization of the Mott insulator Sr$_{0.5}$Ba$_{0.5}$MnO$_{3}$. We predict a ferroelectric polarization of $\\simeq 16.5 \\mu C/cm^2$ in the high temperature paramagnetic phase and recover the measured value of $\\simeq 13.3 \\mu C/cm^2$ in the low temperature antiferromagnetic phase. Our calculations reveal that the driving force for the ferroel","authors_text":"A.-M.S. Tremblay, G. Kotliar, R.
