First of all, it is unsafe. File names for papers downloaded from 
various sources may have enough fancy characters including double 
quotes, etc. having special meaning for shell.

Use at least `shell-quote-argument' instead of adding double quotes.

Depending on your OS I suggest to have a look at the implementation of 
`browse-url-xdg-open', `browse-url-default-macosx-browser', 
`browse-url-default-windows-browser' for an example how to start 
external viewer process.

Is there a reason to avoid emacs global or even system global settings 
obtained through mailcap.el? While `mailcap-view-file' is quite new 
addition, the function was inspired by `org-open-file' and the latter 
queries mailcap settings.

Actually I suspect that there may be some problems especially with 
Emacs-27 (see "org--file-default-apps" thread), but the consequences is 
not clear for me yet.
