Abstract
Direct detection of relic neutrinos in a beta-decay experiment is an ambitious goal that has long been beyond the reach of available technology. One of the most challenging practical difficulties for such an experiment is managing a large amount of radioactive material without compromising the energy resolution required to distinguish useful events from the substantial beta-decay background. The PTOLEMY project offers an innovative solution to this problem by depositing radioactive material on graphene. While this approach is expected to address the main challenge, it introduces new issues due to the proximity of the beta decayers to a solid-state system. In this work, we focus on the effect of the shakeup of the graphene electron system caused by a beta-decay event. We calculate the distortion of the relic neutrino peaks resulting from this shakeup, analyze the impact of the distortion on the visibility of neutrino capture events, and discuss potential technological solutions to enhance the visibility of these events.

Strengths
1- improved clarity of the manuscript.
2- thorough discussion of the consequences of entanglement between beta-electron and the rest of the system
Weaknesses
1- too technical in some parts
Report
In the second version of their manuscript, the authors have made an effort to accommodate my requests and clarify my doubts.
I think the paper has now improved in clarity and I have personally understood better the physics behind.
I am glad to recommend it for publication.
Recommendation
Publish (easily meets expectations and criteria for this Journal; among top 50%)
