How to make citation for a new paper in arxiv?
As Christian mentions, there are already BibTex entries for your articles.

On NASA ADS: http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2017arXiv170309438T&amp;data_type=BIBTEX&amp;db_key=PRE&amp;nocookieset=1

On the University of Trier database: http://dblp.uni-trier.de/rec/bibtex/journals/corr/TatarchenkoDB17 

Whether you use one of these or wait for the one from Google Scholar, the main issue will be how your bibtex style renders the citation. You may need to adjust the fields "journal", "pages" and/or "eprint" to obtain a suitable result.

EDIT: I found those links on the arxiv page https://arxiv.org/abs/1703.09438 on the right column, as mentioned by ff524
