SUMMARY:How d-wave pair fluctuations arise from strong electronic corr
 elations\, R. G. Herb Condensed Matter Seminar\, William Putikka\, Ohi
 o State University
DESCRIPTION:Superfluid behavior is relatively common in strongly corre
 lated fermion systems\, suggesting there is a common reason for this b
 ehavior rooted in the strong correlations. In previous calculations I 
 found d-wave pair fluctuations in the 2D t-J model on a square lattice
 . Having pair fluctuations in a well-defined strongly correlated model
  allows for a detailed examination of the model's properties for the m
 odel parameters where the pair fluctuations are strongest. From this a
 nalysis I propose a robust process for producing pair fluctuations by 
 strong correlations. As part of the analysis I find that d-wave pair f
 luctuations are not due to antiferromagnetic spin fluctuations\, inste
 ad the AF fluctuations compete with the pair fluctuations. I will also
  discuss how these ideas may generalize across a broader range of stro
 ngly correlated systems.<br>
