Accession number: 20141017417949 Title: Influence of magnetic field and lo phonon effects on the spin polarization state energy of strong-coupling bipolaron in a quantum dot Authors: Eerdunchaolu1; Han, Chao1; Xin, Wei1 Email author xinweigood@hotmail.com; Wuyunqimuge2 Author affiliation: 1 Institute of Condensed Matter Physics, Hebei Normal University of Science and Technology, Qinhuangdao 066004, China 2 College of Physics and Electronic Information, Inner Mongolia University for Nationalities, Tongliao 028043, China Corresponding author: Xin, W. (xinweigood@hotmail.com) Source title: Journal of Low Temperature Physics Abbreviated source title: J. Low Temp. Phys. Volume: 174 Issue: 5-6 Issue date: March 2014 Publication year: 2014 Pages: 301-310 Language: English ISSN: 00222291 E-ISSN: 15737357 CODEN: JLTPAC Document type: Journal article (JA) Publisher: Springer New York, 233 Spring Street, New York, NY 10013-1578, United States Abstract: On the basis of Lee-Low-Pines unitary transformation, the influence of magnetic field and LO phonon effects on the energy of spin polarization states of strong-coupling bipolarons in a quantum dot (QD) is studied by using the variational method of Pekar type. The variations of the ground state energy E0 and the first excited state the energy E 1 of bipolarons in a two-dimensional QD with the confinement strength of QDs ω 0, dielectric constant ratio η, electron-phonon coupling strength α and cyclotron resonance frequency of the magnetic field ωc are derived when the influence of the spin and external magnetic field is taken into account. The results show that both energies of the ground and first excited states (E 0 and E1) consist of four parts: the single-particle energy of electrons Ee, Coulomb interaction energy between two electrons Ec, interaction energy between the electron spin and magnetic field ES and interaction energy between the electron and phonon E e - ph; the energy level of the first excited state E1 splits into two lines as E 1 (1 + 1) and E 1 (1 - 1) due to the interaction between the single-particle "orbital" motion and magnetic field, and each energy level of the ground and first excited states splits into three "fine structures" caused by the interaction between the electron spin and magnetic field; the value of E e - ph is always less than zero and its absolute value increases with increasing ω 0, α and ωc; the effect of the interaction between the electron and phonon is favorable to forming the binding bipolaron, but the existence of the confinement potential and Coulomb repulsive energy between electrons goes against that; the bipolaron with energy E 1 (1 - 1) is easier and more stable in the binding state than that with E 1 (1 + 1). © 2013 Springer Science+Business Media New York.
