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…

Spectroscopic signatures of next-nearest-neighbor hopping in the charge and spin dynamics of doped one-dimensional antiferromagnets
Umesh Kumar, Gregory Price, Kenneth Stiwinter +3
We study the impact of next-nearest-neighbor (nnn) hopping on the low-energy collective excitations of strongly correlated doped antiferromagnetic cuprate spin chains. Specifically…
