Strongly correlated electrons represent a vibrant field that continues to expand its horizon. This talk will focus on several issues that are of extensive current interest to a wide variety of correlated electron materials and are epitomized by the studies on heavy fermion systems. I will address quantum criticality and the unusual magnetic and superconducting phases that arise at the border of local-moment-based metallic antiferromagnetism, and a global phase diagram that organizes the physics beyond the Landau framework. I will also discuss the effect of spin-orbit coupling in this context, including the emergence of a strongly correlated Weyl semimetal whose key signature has been realized in a candidate material.
