The nearly 80-year-old correlated electron problems remain largely unsolved; with one stunning success being BCS electron-phonon mediated conventional superconductivity. There are dozens of families of superconductors that are unconventional, including the high-Tc cuprates, iron-based, and heavy fermion superconductors. Although these materials are disparate in many of their properties, some of their fundamental characteristics are strikingly similar, including their ubiquitous phase diagram, with intriguing correlated-electron (non-Fermi liquid) phases at temperatures above their superconducting phase transition. These remain among the greatest unsolved problems in physics today; and I will present an analogy stressing this. I start with a short overview of the US National MagLab and finish showing our own recent work identifying an exotic pairing mechanism in the heavy fermion CeCoIn5.
Laura Greene is the chief scientist at the National MagLab and the Francis Eppes Professor of Physics at Florida State University. Her research is in experimental condensed matter physics with a focus on quantum materials, including topological matter and high-temperature superconductors. As the 2017 president of the American Physical Society (APS), Laura’s theme was science diplomacy and human rights. She serves on the Board of Directors of the American Association for the Advancement of Science and is a vice president of the International Union of Pure and Applied Physics. A champion for diversity, she works with teams that promote the success of women and young scientists, particularly in developing countries. She plays many leadership advisory roles for funding agents and institutions and recently was a co-chair of the National Academy’s consensus report: “Frontiers of Materials Research: A Decadal Survey.” Laura is a member of the US National Academy of Science, and a fellow of the American Academy of Arts and Sciences, the Institute of Physics (UK), the American Association for the Advancement of Science, and the APS. Her recognitions include the APS “2019 Five-Sigma Physicist award for science advocacy, The 2019 Gold Medal Award from the Tallahassee Scientific Society a Guggenheim fellowship, the Lawrence Award for Materials Research, and the Maria Goeppert-Mayer Award. She very recently received the APS Five Sigma Physicist Award for Advocacy. Laura has co-authored over 200 publications and presented over 600 invited and plenary talks.
