Theory of the magnetic and metal-insulator transitions in RNiO3 bulk and layered structures

Bayo Lau, Andrew J. Millis

A slave rotor-Hartree Fock formalism is presented for studying the properties of the p-d model describing perovskite transition metal oxides, and a flexible and efficient numerical…

Reply to "Comment on 'High-Spin Polaron in Lightly Doped CuO Planes'"

Bayo Lau, Mona Berciu, George A. Sawatzky

In arXiv:1108.5413v1, Lee and Lee use several comparisons to argue that the physics of the three-band model found (Phys. Rev. Lett. 106 036401 (2011)) can be explained in the one-b…

A computational approach to a doped antiferromagnet: correlations between two spin-polarons in the lightly doped CuO plane

Bayo Lau, Mona Berciu, George. A. Sawatzky

We extend the methods recently introduced in Phys. Rev. Lett. 106 036401 (2011) to investigate correlations between two spin-polarons in a quasi-two-dimensional CuO2 layer. The low…

High-spin polaron in lightly doped CuO planes

Bayo Lau, Mona Berciu, George A. Sawatzky

We device and investigate numerically a minimal yet detailed spin polaron model that describes lightly doped CuO layers. The low-energy physics of a hole is studied by total-sp…

Computational scheme for the spin-1/2 square lattice Heisenberg antiferromagnet based on an octapartite description of the square lattice

Bayo Lau, Mona Berciu, George A. Sawatzky

We introduce a novel parametrization scheme for the Hilbert space of a spin-1/2 Heisenberg antiferromagnet (AFM) based on an octapartite description of the square lattice. Our form…

Single polaron properties of the breathing-mode Hamiltonian

Bayo Lau, Mona Berciu, George A. Sawatzky

We investigate numerically various properties of the one-dimensional (1D) breathing-mode polaron. We use an extension of a variational scheme to compute the energies and wave-funct…
