SUMMARY:FFLO and pair density wave superconductivity\, R. G. Herb Cond
 ensed Matter Seminar\, Daniel Agterberg\, UW-Milwaukee
DESCRIPTION:With the groundbreaking work of Fulde\, Ferrell\, Larkin a
 nd Ovchinnikov (FFLO)\, it was realized that superconducting/superflui
 d order can also break translational invariance\, leading to a phase i
 n which the Cooper pairs develop a coherent periodic spatially oscilla
 ting structure. Such pair density wave (PDW) superconductivity/superfl
 uidity has become relevant in a diverse range of systems\, including c
 uprates\, organic superconductors\, heavy-fermion superconductors\, co
 ld atoms\, and high-density quark matter. In this talk I discuss recen
 t theoretical developments on PDW/FFLO phases.  This will include both
  a discussion of the microscopic origin of such phases in materials wi
 th and without inversion symmetry and a phenomenological description o
 f these phases highlighting the role of fractional vortices and therma
 l fluctuations.
