  • $\begingroup$ not sure all tags are returned. For instance the tag: coherent-states is not listed. $\endgroup$ Commented Aug 17, 2023 at 22:13
  • $\begingroup$ @ZeroTheHero It lists the top few. coherent-states has id 1994, see data.stackexchange.com/physics/query/edit/1776411 $\endgroup$

    $\begingroup$ Presumably the first tag is the alphabetically-first tag on /q/1 on the site. Which, indeed, should be quantum-spin. $\endgroup$ Commented Aug 20, 2023 at 23:48
