SUMMARY:Electronic Liquid Crystalline Phases in Highly Correlated Elec
 tronic Systems\, Physics Department Colloquium\, Steven Kivelson\, Sta
 nford University
DESCRIPTION:In one extreme\, where the interactions are sufficiently w
 eak compared to the interactions\, electrons form a "Fermi liquid" - t
 he state that accounts for the properties of simple metals.  In the ot
 her extreme\, where the interactions are dominant\, the electrons form
  various "Mott" insulating or "Wigner crystalline" phases\, often char
 acterized by broken spatial and/or magnetic symmetries.  Corresponding
  charge and/or magnetically ordered insulating phases are common in na
 ture.  Between these two extremes lie highly correlated electronic flu
 ids\, and correspondingly a host of interesting and perplexing materia
 ls\, including such diverse systems as the cuprate and iron-based high
  temperature superconductors\, the failed metamagnet Sr<sub>3</sub>Ru<
 sub>2</sub>O<sub>7</sub>\, and a variety of quantum Hall fluids.  Some
  insight into this rich intermediate coupling regime can be obtained f
 rom viewing it as a partially melted electron solid\, rather than as a
  strongly interacting gas.  Here\, analogies with the liquid crystalli
 ne phases of complex classical fluids provide useful guidance for a ne
 w approach to this key problem in condensed matter physics.
