Abstract
We use a mobile impurity or depleton model to study elementary excitations in one-dimensional integrable systems. For Lieb-Liniger and bosonic Yang-Gaudin models we express two phenomenological parameters characterising renormalised inter- actions of mobile impurities with superfluid background: the number of depleted particles, $N$ and the superfluid phase drop $\pi J$ in terms of the corresponding Bethe Ansatz solution and demonstrate, in the leading order, the absence of two-phonon scattering resulting in vanishing rates of inelastic processes such as viscosity experienced by the mobile impurities
Author comments upon resubmission
We would like to resubmit our manuscript after some minor revisions.
The revised version is now available at http://arxiv.org/abs/1701.00810v3.
We hope that the revised manuscript is now suitable for publication in
SciPost.
Yours sincerely,
Andrew S. Campbell

List of changes
- The phrase "The equivalence of these results to those obtained in ..." is
removed and the preceding sentence is modified.
- Yang-Gaudin model is replaced by "bosonic Yang-Gaudin model" everywhere in the
text.
- Reference [38] added.
- We have modified the sentence around Eq. (60).
