Characterization of local symmetry breaking in superconducting La2-xBaxCuO4 & La2-xSrxCuO4

Abstract: The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the electronic population at the fermi level) regime that may be related to a broken-symmetry electronic state competing with HTSC. Recent experimental evidence supports earlier suggestions that liquid crystal-like electronic states might exist in the PG regime and be critical to further understanding of HTSC. If these exotic electronic states exist, it is expected that they would cause the local positions of atoms to differ from those in the average crystal structure. We aim to explore this idea by looking at two HTSCs using neutron total scattering. This technique can probe both the average crystal structure and local deviations from it, allowing tracking of structural footprints of broken-symmetry electronic state.
