Abstract: B02.00008 : Optimized pairing from repulsive interactions in Fermi-Hubbard ladders and its static and dynamic signatures*
In this talk we will present such results for the Fermi-Hubbard ladder, which is proven to have unconventional pairing, and that allows us to optimize this pairing via changes in ladder structure and interactions based on highly accurate numerical theory such as matrix-product-state-based methods. We further demonstrate quantitatively how the temperature ranges at which repulsively mediated pairing may be experimentally observable is very strongly dependent on these optimizations, and how it may be detected with established techniques in both the static regime as well as via dynamically generated excitations.
