Abstract: V40.00008 : A two-pronged approach to the cuprate pseudogap: A comparison of mode-coupling and first-principles (SCAN) results
4:18 PM–4:30 PM
The contrasting behaviors of YBCO6 and YBCO7 are reminiscent of the Mott-Slater crossover found in a mode-coupling model of the cuprates. I will demonstrate how these two approaches illuminate each other, leading to a picture of the pseudogap as a gapped paramagnetic metal with only short-range order (SRO) over a broad temperature range. This work provides a realistic model for the cuprate pseudogap phase with implications for superconducting pairing.
