TL;DR: In this paper, the resolution of a recurrence tracking microscope (RTM) is enhanced to subnanometer scale by using a continuous wavelet transform (CWT) to read information on frequency bands, time of revivals, and corresponding time of fractional revivals.
Abstract: Based on continuous wavelet transform (CWT), we show that the resolution of a recurrence tracking microscope (RTM) is enhanced to subnanometer scale. Our approach helps us to read information on frequency bands, time of revivals, and corresponding time of fractional revivals more accurately. We demonstrate that wavelet analysis provides a deeper information on the phenomena of quantum recurrences in general. Our analytical results show very good agreement with numerical results based on experimental parameters.

TL;DR: In this article, a recurrence tracing microscope based on the reflection of cold atoms from two magnetic mirrors placed in parallel is introduced, where a cantilever is attached perpendicularly to one of the two mirrors at the lower end that probes surface structures.
Abstract: We introduce a recurrence tracing microscope based on the reflection of cold atoms from two magnetic mirrors placed in parallel. A cantilever is attached perpendicularly to one of the two mirrors at the lower end that probes surface structures. The quantum dynamics in the system provides the matter waves to store information on the height and spacing between the nanostructures. We use the recurrence tracking microscope in static and dynamic modes to study arbitrary and periodic nanostructures.

TL;DR: In this paper, an evanescent wave trap is formed by the total internal reflection of two laser fields having different signs of detuning and penetration depths into the vacuum, in order to scan nanostructures on a surface.
Abstract: In order to scan nanostructures on a surface, we present a new recurrence tracking microscope based on an atomic trap. An evanescent wave trap is formed by the total internal reflection of two laser fields having different signs of detuning and penetration depths into the vacuum. The microscope employs the quantum recurrence phenomena of trapped atoms. Recurrence times depend on the initial energy of the wave packet in the trap and vary following the nanostructures on the surface under investigation.

TL;DR: The recurrence tracking microscope for probing nanostructures on a surface is based on the quantum recurrence phenomenon as mentioned in this paper, and the times at which the recurrences occur depend on the initial energy of the bouncing condensates above the atomic mirror, which change with the density of condensed atoms.
Abstract: The recurrence tracking microscope for probing nanostructures on a surface is based on the quantum recurrence phenomenon We report that condensed atoms bouncing off on the atomic mirror, connected to a cantilever, modify the quantum recurrences The times at which the recurrences occur depend on the initial energy of the bouncing condensates above the atomic mirror, which change with the density of condensed atoms

TL;DR: In this article, a recurrence tracking microscope was used to study the quantum revival time of the wave packet and probe nanostructures on a surface, and it was shown that the change in the initial height of the nanoparticles is due to the variation in the revival times at different positions of the cantilever.
Abstract: A recurrence tracking microscope works on quantum recurrence phenomena of the wave packet and probes nanostructures on a surface. The important advantage of condensed atoms over cold atoms is the very small distribution size due to the atom–atom interactions. We report a more precise measurement of the quantum revival time. For small nonlinear interatomic interactions, there is a small change in quantum revival times; however, as the interaction becomes stronger, we find visible changes in the revival time. The change in the initial height of the nanoparticles is due to the variation in the revival times at different positions of the cantilever.
