Effect of Van der Waals Force on Wave Packet Dynamics

Abstract

In light of the fact that nanotechnologyisunquestionablyafantastic f ield of science. It has numerous uses in engineering, science, and defence. It is necessary to gather data on solid surfaces for research and technology in the fields of surface and material sciences. It takes a microscope based on the laws of quantum mechanics to see the nano structure on the surface of a solid. Atool that can be used to examine solid surfaces is the recurrence tracking microscope. An atomic cloud is bounced off on atomic mirror that is created as a result of the interaction between the force of gravity and optical force, revealing quantum recurrences of ma terial wave packets. A cantilever is attached to the opposite side of this atomic mirror. The atom’s initial potential energy determines how long recurrences last when they are bouncing off on atomic mirror. As the structural change manifests itself beneath the can tilever on a solid’s surface, the original height of the atoms will shift. When an atomic cloud in a recurrence tracking microscope reaches the insulator’s surface, a Van der Waals force exerted on the cloud can stop the phenomenon of quantum recurrences. In this thesis, by introducing the vanderwaals force in to the system we are attempting to examine its effect on the recurrence tracking microscope
