Effect of Rashba spin-orbit coupling on polaron properties in CdSe nanowire under electric field

In the frame of Lee-Low-Pines variational theory the effect of the Rashba spin-orbit coupling (SOC) on the properties of the quasi-one-dimensional Fröhlich polaron in the weak and intermediate coupling limits of the electron-phonon interaction has been studied. Polaron self-energy and effective mass are numerically investigated for the free-standing CdSe nanowire as functions of the Rashba spin-orbit coupling parameter, the confining fequency, the electric field strength and the dielectric constant of the surrounding medium. Our results show that the Rashba SOC can be used as an effective means for controlling polaron states and therefore, we hope that the obtained results will stimulate further experiments in CdSe nanowires.
