If they're right, this is amazing. All these years of reading threads on SFN where monopoles are proclaimed to be impossible... and here they are. I'm now curious to see if someone else will overturn the claims or if their conclusions are truly correct.
(Here's where I wish I could skip a few semesters ahead so I could actually know what the papers are talking about. That could be important.)
