Abstract
We apply the Lee-Low-Pines-Huybrechts variational method to study the properties of the
two and three dimensional bipolaron in a quantum dot. The ground-state (GS) and two types of
excited-state energies of the Fröhlich bipolaron for the whole range of electron-phonon coupling
constants can be obtained. Compared with the Franck-Condon excited state, the first relaxed excited
state has a lower energy. Effects of quantum dot confinement on the excitation energies of the
bipolaron are given.
