Dynamics of electron-electron entanglement in pulsed sinusoidal potentials

The surface acoustic wave (SAW) assisted charge transport represents a highly controllable mean to inject and drive electrons along quasi one-dimensional channels. By means of a numerical approach, here we analyze the effect of the removal of SAW, for a finite time interval, onto the entanglement stemming from the Coulomb scattering between two charged carriers bound in SAW potential itself. We find that the particles get quickly entangled thus confirming that the SAW driven transport in low-dimensional semiconductor structures permits to suppress the effects of electron-electron correlation due to the Coulomb interaction.
