Zero temperature momentum distribution of an impurity in a polaron state of one-dimensional Fermi and Tonks-Girardeau gases

Response to Referee 1:

1. Indeed, apart from the title and the abstract, we have mentioned the Tonks-Girardeau bosons only in the conclusions, without much explanation. Now, we are mentioning the Tonks-Girardeau bosons in the beginning of section 2, and give a reference to the section 2 of the work [25].

2. Typos corrected

Response to Referee 2:

1. We understand the logic of the proposed change. However, our point is that sections 3 to 7 are a natural continuation of the section 2 in that they altogether contain the result: the analytic formulas used to describe the momentum distribution function of the impurity. Hence, the reader who only wants the result about the momentum distribution may omit reading the last section 8. The above said, we would like to keep the order of the sections of the manuscript unchanged.

2. We have explained vanishing of the integrals in Eq. (158) in more detail. Furthermore, section 8 contains now only formulas valid for any N. All calculations relevant for the large N limit are put into the appendix A. The title of this appendix has been changed accordingly.

Response to Referee 3:

We have added a paragraph to the "Conclusion" section discussing in brief the experimental findings in ultracold atomic gases related to the observable studied in our manuscript.

Restored overall phase factor in Eq. (66), accidentally erased in the course of the editing of the manuscript. This does not affect any other equation or figure in the manuscript. Some notations are changed around Eqs. (66)-(71), and through the appendix A. Title change for the appendix A.
