DESCRIPTION:Interactions between electrons can lead to electronic liquid c
 rystal states\, which partially break the symmetries of the host crystal. 
 Recent experiments on the pseudogap region of cuprate superconductors poin
 t to an electron nematic phase\, a translationally invariant state which s
 pontaneously breaks the discrete rotational symmetry of the crystal. Howev
 er\, disorder caused by dopant atoms typically induces a domain structure\
 , making the phase difficult to detect using conventional experimental tec
 hniques. Using a mapping of this domain structure to the random field Isin
 g model\, we explore the effects of noise and hysteresis in transport anis
 otropy\, superfluid density\, and scanning tunneling microscopy.
