Abstract: Superfluid behavior is relatively common in strongly correlated fermion systems, suggesting there is a common reason for this behavior 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 model parameters where the pair fluctuations are strongest. From this analysis I propose a robust process for producing pair fluctuations by strong correlations. As part of the analysis I find that d-wave pair fluctuations are not due to antiferromagnetic spin fluctuations, instead the AF fluctuations compete with the pair fluctuations. I will also discuss how these ideas may generalize across a broader range of strongly correlated systems.
