Quantum Control of Exciton Motion in Electric Field

We studied the quantum control of the classical motion of a two-dimensional exciton by optimizing the time-dependent electric field of a stripe-like gate acting on the exciton and inducing its time-dependent quantum dipole moment. We propose a search method that significantly reduces computational requirements while efficiently identifying optimal control parameters. By leveraging this method, we can precisely manipulate the exciton’s final position and velocity over a specified evolution time. These results can be applied for the control of exciton fluxes and populations, and for spatially resolved light emission in two-dimensional semiconducting structures.
