© Published under licence by IOP Publishing Ltd.The Holstein model was used to determine the value of electron-phonon coupling in BaBiO3-based compounds in the framework of the dynamical mean-field theory calculations for various levels of doping with potassium. The results obtained characterize the electron-phonon interaction as strong. The phase diagram of the model was calculated with reference to experimental data.
