“…It is found that cold atoms can be reflected by cavities containing zero number of photons (cavities in vacuum states). Therefore, atom-field interaction can be treated as a scattering process [1][2][3][4][5][6], where cavity acts like a potential for the incident ultracold atoms. Such potentials are referred as vacuum induced potentials and are essentially different from those produced by the far detuned laser fields [7].…”

We study the tunneling and traversal time of ultracold two-level atoms through a high quality microwave cavity containing N − 1 ground state atoms. The phase time of tunneling may be considered as a measure of the time required to traverse the cavity which exhibits both super and subclassical traversal behaviors. Here we examine that superclassical phase time behavior suppresses with the increase in the number of motionless ground state atoms inside the cavity. It happens due to the multipartite influence in the interaction that traps the incident atom into its upper state such that it does not observe any induced potential. Accordingly, for larger atomic samples, the incident atoms in the initial excited states get perfect transmission and tunnel through the cavity nearly with the same speed as they would have moved through a free space. This is true for any width of potential and the particle's speed provided that the centerof-mass energy of the incident particle lies in the classically forbidden range.
