Abstract
We present a recurrence tracking microscope (RTM) based on a magnetic mirror to probe micro and nanostructures on a surface. We modify existing RTM by introducing a magnetic mirror rather than the optical surface that produces exponentially decaying potential above the mirror surface in the vertical direction. Therefore, the cold atom evolves in a potential made up by the magnetic and gravitational fields. For a rapid decay of the magnetic field, the effective form of the potential becomes that of a triangular well. Hence, the coherent evolution of the atom above the magnetic trampoline reveals information on height and spacing between the surface structures. Presently available experimental technology makes it possible to develop the device in the laboratory.
