We present a double quantum wire system containing a coupling element in the middle barrier between the two parallel quantum wires. We explicitly account for the finite length of the double quantum wire with a time-dependent switching-on potential coupling the double-wire system and the leads. By tuning the magnetic field and the coupling window between the wires, we analyze the time-dependent current and the charge distribution of the Coulomb interacting many-electron states in order to explore inter-wire transfer effects for developing efficient quantum interference nanoelectronics.
