DESCRIPTION:Interactions can lead to a wide variety of ordered states in ma
 terials. Phase transitions in which local atomic states develop spontaneou
 s high rank multipole order provides a particularly rich arena for new ins
 ights. A key element in the study of such systems is the ability to couple
  to the associated order parameter. At its heart\, this colloquium will be
  about symmetry and thermodynamics. I will describe how one can couple to 
 a variety of different multipolar states\, motivating new methodologies to
  measure a fundamental thermodynamic material property\, the multipole sus
 ceptibility. One can also identify effective transverse fields\, which\, w
 hen applied inside the ordered state\, induce quantum fluctuations and can
  drive a multipolar quantum phase transition. I will explain the very spec
 ial roles that strain can play for each of the cases\, and will outline ne
 w experimental approaches in which the materials 'feel the strain' in diff
 erent ways. Even while we manipulate the crystal lattice to tune electroni
 c order\, hyperfine interactions are not always completely innocent. Along
  the way I will introduce the special case of an electro-nuclear quantum p
 hase transition.
