Today’s colloquium speaker is Laura Greene, president of the American Physical Society and head of the National High Magnetic Field Laboratory at Florida State University. She is an expert in strongly correlated fermionic systems. When high-temperature superconductors were being discovered, she and her collaborators were among the first to note the importance of oxygen and the crystalline structures of copper-oxides. She is also a strong proponent for equality for women and minorities.
Her lecture today is titled “Correlated Electrons, the Dark Energy of Condensed Matter Physics.” It takes place at 4 p.m. in One West.
The nearly 80-year-old “correlated electron problem” remains largely unsolved, with one stunning success being conventional superconductivity. There still exists dozens of families of superconductors that we do not understand, classified as unconventional, including the high-temperature cuprate superconductors. These materials exhibit a ubiquitous phase diagram, with regions in which strongly correlated electron states exist, whose properties remain unexplained. After a short introduction to the MagLab, Greene will define conventional and unconventional superconductivity and discuss how many researchers believe that understanding their enigmatic electronic phases will lead us to the predictive design of better superconductors. She will also explain the analogy in the talk title.
