Abstract
A number of materials in the focus of current theoretical and experimental efforts exhibit intertwined order There the pattern of symmetry breaking is such that two originally unrelated symmetries are no longer independent in the ordered phase One common example is spin density wave order which intertwines translations with spin rotations A closely related order arises in modulated superconductors which intertwine translations with superconducting phase rotations In the presence of imperfections inherent to any real system the nature of these states changes dramatically In this talk I will introduce new phases of matter spin and pair density wave glasses which arise as a consequence These states are both spin glasses and symmetry broken phases at the same time their measured nature depends on the experimental probe In particular I will describe the unusual dynamical response characteristic of these new phases which is extremely slow glassy in certain variables while it is fast in others Refreshments are served at 3:20pm
