From High Temperature Superconductivity to Quantum Spin Liquid: Progress in Strong Correlation Physics

This is a fascinating review article by Patrick Lee of MIT[1], even if you don't agree with his take on the mechanism of cuprate superconductivity. He covers the outstanding issue in strongly-correlated electron system, which is the main area of study in condensed matter physics since it covers essentially that whole field of study.

What is interesting is that at the end of the article, he has a question-answer section that addresses specific issues and his take on the answer. This is always something I like to read because even if you disagree with him, at least you know clearly where he stands and why he disagrees. In many instances, it can be vague on what exactly people are disagreeing on. Here, it is rather clear.

In any case, I would think anyone in this field of study would want to read this article. At the very least, it'll get you up to speed on the theoretical progress in this area.
