[Solved] Bibtex not putting a space between the author name and “and”

Light Yagmi Asks: Bibtex not putting a space between the author name and “and”
I am working on bibliography with Bibtex, but have encountered a problem.

When there are two authors, Bibtex will not put a space between the author’s name and the “and”. If you check the attached image, you can easily see the problem.

How do you solve this problem? I am using RevTex 4.2 on Overleaf.com, compiled with “Latex compiler” and Tex live version 2020.


  • It seems that the bibtex style file is apsrev4-2.bst because the “prx” option is selected.
  • I have copied the bibtex source from Google scholar and here is what is shown in the image:

  title={Extracting work from a single heat bath through feedback},
  author={Abreu, David and Seifert, Udo},
  journal={EPL (Europhysics Letters)},
  publisher={IOP Publishing}

  title={Entropy production and fluctuation theorems under feedback control: the molecular refrigerator model revisited},
  author={Munakata, T and Rosinberg, ML},
  journal={Journal of Statistical Mechanics: Theory and Experiment},
  publisher={IOP Publishing}
