Is there a way to search for more recent papers than the one I'm currently reading?
A simple way that I usually follow to find newer papers about the same topic is using google scholar. Google scholar gives you the ability to find papers that cited the paper you are interested in, and those papers are usually published after the paper you are interest in has been published (i.e. more recent work).

For the example you provided in your comment, google scholar gives me 57 articles/results that cited your example
