Title:
Two-site Hubbard molecule with a spinless electron-positron pair
Authors:
Cossu, Fabrizio; Schuster, Cosima; Schwingenschlögl, Udo ( 0000-0003-4179-7231 )
Abstract:
We determine the eigenvalues of the two-site Hubbard molecule with one electron and one positron to describe the characteristics of electron-positron interactions in solids. While the effect of hopping is, in general, opposite to the effect of on-site interaction, we find a complex scenario for the electron-positron pair with a non-vanishing potential drop. We give analytical solutions and discuss the combined effects of the model parameters.
