Abstract

We present a protocol based on the interplay between superradiance and superabsorption to achieve the coherent deflection of an atomic sample due to the momentum transfer from the atoms to a cavity field. The coherent character of this momentum transfer, causing the atomic sample to deflect as a whole, follows from the collective nature of the atomic superradiant pulse and its superabsorption by the cavity field. The protocol is then used for the construction of positional mesoscopic atomic superpositions.

Reports on this Submission

Report #1 by Anonymous (Referee 1) on 2025-1-9 (Invited Report)

Strengths

1 - The manuscript by da Silva et al. presents a new protocol to achieve coherent deflection of an atomic sample coupled with the optical mode of a high finesse cavity, due to coherent momentum transfer.
2- the protocol can find application in the realization of mesoscopic atomic superpositions

Weaknesses

1- A simple, conceptual design of the system being studied is missing, only references to other papers are given.

2-no numerical example based on a realizable atomic system is given

Report

the paper is interesting and meets the criteria of the journal, before publication, I'd invite the authors to major changes as listed above.

Requested changes

While the paper is interesting and meets the criteria of the journal, before publication, I'd invite the authors to do:

1- spelling cross-check of the manuscript

Here are a few examples of misprints that I've found:
l. 36 "antecipated"
l.71 "rulled out"
l.125 "senoidal functions"
l. 128 "procedure"
...

2- cross-check definitions of measurable quantities introduced in the manuscript,
as, for example in:
- eq. 1 \omega and \omega_k not defined

For this, a schematic view of the experimental system under study might clarify.

3- Add practical, experimental numerical estimation of realizable systems to check in which conditions different effects/regimes (damped, underdamped, ...) might be experimentally observable.
