R. G. Herb Condensed Matter Seminar
How d-wave pair fluctuations arise from strong electronic correlations
Time: 10:00 am
Place: 5310 Chamberlin
Speaker: William Putikka, Ohio State University
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.
