Inversion symmetry breaking in bilayer multi-orbital Hubbard model with impurity approximation
Chenye Qin, Mi Jiang
We investigated the Cu/Ni-O bilayer multi-orbital Hubbard model with Cu/Ni impurity approximation embedded in the O lattice by incorporating the 3d multiplet structure co…
Stabilization of singlet hole-doped state in infinite-layer nickelate superconductors
Mi Jiang, Mona Berciu, George A. Sawatzky
Motivated by the recent X-ray absorption spectroscopy (XAS) and resonant inelastic X-ray scattering (RIXS) experiments, we use a detailed impurity model to explore the nature of th…
Polaron and bipolaron tendencies in a semiclassical model for hole-doped bismuthates
Mi Jiang, George A. Sawatzky, Mona Berciu +1
Bismuth perovskites ABiO (A = Sr, Ba) host a variety of peculiar phenomena including bond-disproportionated insulating phases and high-temperature superconductivity upon hole d…
Antiferromagnetism mediated by heavy electrons: singlet shielding vs "high-order" RKKY
Mi Jiang
Can the antiferromagnetic (AF) order be induced via the local moments' hybridization with the heavy electrons instead of conduction electrons? We address this intriguingly fundamen…
Relevance of Cu-3d multiplet structure in models of high Tc cuprates
Mi Jiang, Mirko Moeller, Mona Berciu +1
We revisit the problem of the spectra of two holes in a CuO layer, modeled as a Cu-d impurity with full multiplet structure coupled to a full O-2p band as an approximat…
Tuning topological orders by a conical magnetic field in the Kitaev model
Ming-Hong Jiang, Shuang Liang, Wei Chen +3
We show that a conical magnetic field can be used to tune the topological order and hence anyon excitations of the quantum spin liquid in the isot…
