In this paper, we investigate the influence of an electric field on the ground state energy of a polaron in a spherical semiconductor quantum dot (QD) using the modified Lee Low Pines (LLP) method. The numerical results show an increase of the ground state energy with the increas...

Yang et al. [1] assume sea level rise induced by global warming is real, and that sea levels may rise by 1 meter by 2100. They then go on to derive ecological conclusions from these assumptions. There is of course no foundation for the ecological speculation if the basic assumpt...
