Signatures of symmetry-stabilized Dirac fermions in correlated oxide CaNbO3 thin films
Yunkyu Park, Seoung-Hun Kang, Jeongkeun Song +11
Symmetry-protected electronic states in correlated oxides offer a route to combining topology, lattice tunability, and many-body interactions, but creating such topological electro…
Atomic ironing for conformal interfaces in freestanding oxide nanomembranes
Jeongkeun Song, Keaghan Knight, Keun-Yeol Park +7
Atomically well-defined interfaces are essential for realizing functional interlayer coupling in stacked and twisted oxide heterostructures, yet transferred freestanding oxides can…
Anomalous stabilization of excitons by metallic proximity
Jeongkeun Song, Uksam Choi, Shan Lin +6
Metallic environments are generally expected to suppress excitons through strong dielectric screening, yet their influence can differ in composite systems where metallic and insula…
Orbital-selective oxygen holes in cuprate ladders beyond the Zhang-Rice paradigm
Chengyun Hua, Tianran Chen, Isaac C. Ownby +13
The electronic structure of the spin-ladder cuprate Sr14Cu24O41 challenges the presumed universality of the Zhang-Rice singlet (ZRS) framework and models based exclusively on Cu-O…
Nanoscale magnetic ordering dynamics in a high Curie temperature ferromagnet
Yueh-Chun Wu, Gábor B. Halász, Joshua T. Damron +11
Thermally driven transitions between ferromagnetic and paramagnetic phases are characterized by critical behavior with divergent susceptibilities, long-range correlations, and spin…
