Quantum Numerical Control of Atom-Ion Collision in Intense Laser Field

In this work, p+H (proton hydrogen) atom-ion collision is considered as a quantum control objective through solving a quantum system described by time dependent Schrodinger equation. For different internuclear distances, the colliding particles are controlled via applying an appropriate intense laser field. It means that one can control certain particle collision in the viewpoint of quantum mechanics at the atomic scale. It is possible to achieve the quantum control of particular colliding process theoretically and computationally, although the realization for poly-particles collision are fairly inadequate. Furthermore, the enhanced ionization rate reaching maximum at a critical internuclear distance is also surveyed together in this way.
