Abstract In this article, we consider an extremely intense laser, enclosed by an atom interferometer. The gravitational potential generated from the high-intensity laser is solved from the Einstein field equation under the Newtonian limit. We compute the strength of the gravitational force and study the feasibility of measuring the force by the atom interferometer. The intense laser field from the laser pulse can induce a phase change in the interferometer with Bose-Einstein condensates. We push up the sensitivity limit of the interferometer with Bose-Einstein condensates by spin-squeezing effect and determine the sensitivity gap for measuring the gravitational effect from intense laser by atom interferometer.

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.
