I'm surprised that noone has mentioned the case of Igor and Grichka Bogdanov here. These were borderline literary theorists that actually did have a complete nonsense physics article published.
Maybe only sci/fi critics? Also I once tried to read their papers and it reminded me of experiences where I've tried to read lit-crit. There were some superficial stylistic similarities, between the two.
