I am looking for more recently-written works (either major papers or review articles) on holographic superconductivity, preferably from 2019 or 2020. The main reviews I know are the following:
Sean A. Hartnoll, Christopher P. Herzog, Gary T. Horowitz, "Holographic Superconductors" (2008)
Gary T. Horowitz, "Introduction to Holographic Superconductors" (2010)
These are very good reviews (and they similarly list a large quantity of references), but I would prefer more contemporary major works or reviews. I would also be interested to see any more recent experimental confirmation of the holographic predictions.
