Abstract

The effect of electron-phonon coupling on the formation of bipolarons is considered in both adiabatic and antiadiabatic regimes. Within the two-site Holstein-Hubbard model, it is shown that fast phonons can influence the formation for both repulsive and attractive effective on-site interactions.

Keywords

bipolarons; electron-phonon coupling
