  Electronic behavior of a 1D Aubry chain with Hubbard interaction is
critically analyzed in presence of electric field. Multiple energy bands are
generated as a result of Hubbard correlation and Aubry potential, and, within
these bands localized states are developed under the application of electric
field. Within a tight-binding framework we compute electronic transmission
probability and average density of states using Green's function approach where
the interaction parameter is treated under Hartree-Fock mean field scheme. From
our analysis we find that selective transmission can be obtained by tuning
injecting electron energy, and thus, the present model can be utilized as a
controlled switching device.
