The many correlated electron problems remain largely unsolved after decades; with one stunning success being BCS electron-phonon mediated conventional superconductivity. The Cooper pairing mechanisms of the dozens of families of unconventional superconductors, including the high-Tc cuprate, iron based, and heavy fermion superconductors remain elusive and quite varied. But some of their fundamental characteristics are strikingly similar, including their ubiquitous phase diagram, with intriguing, correlated electron (non-Fermi liquid) phases that break the symmetry of their underlying lattice at temperatures well above T_c. These correlated phases remain among the greatest unsolved problems in physics; and I will present an analogy stressing that. I will start with an overview of the US National MagLab and finish a glimpse of some of my own recent work possibly identifying a possible new pairing mechanism in a heavy-fermion superconductor.
