Abstract
On the fundamental basis of the modified Lee Low Pines theoretical method, we study analytically the stability and coherence of magneto-bipolaron in asymmetric quantum dot (QD) under the laser field. It is observed that, the bipolaron stability strongly depends on the electron–phonon coupling constant, magnetic field, laser frequency and high laser field strength. It is shown that, the laser field can trap and cool the magneto-bipolaron under certain conditions. The laser and magnetic field strongly affect the coherence time of bipolaron. This study enables to construct superconducting materials.
