Mechanism of basal-plane antiferromagnetism in the spin-orbit driven iridate Ba2IrO4

By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5d5 j 1/2 layered material Ba2IrO4. While the calculated anisotropic couplings come

Models and materials for generalized Kitaev magnetism

The mechanism proposed by Jackeli and Khaliullin to identify Kitaev materials based on spin-orbital dependent bond interactions is analyzed and a comprehensive overview of its implications in real materials is provided.

Time-reversal symmetry breaking hidden order in Sr2(Ir,Rh)O4

A hidden magnetic order is reported in pure and doped Sr2(Ir,Rh)O4, distinct from the usual antiferromagnetic pseudospin ordering, and it is found that time-reversal symmetry is broken while the lattice translation invariance is preserved in the hidden order phase.

Twisted Hubbard model for Sr2IrO4: magnetism and possible high temperature superconductivity.

It is proposed that (electron-)doping Sr(2)IrO(4) can potentially realize high-temperature superconductivity and derive several simple facts based on this mapping and the known results about the Hubbard model and the cuprates.

Square Lattice Iridates

Over the past few years, Sr2IrO4, a single-layer member of the Ruddlesden–Popper series iridates, has received much attention as a close analog of cuprate high-temperature superconductors. Although

Theory of the pseudogap state of the cuprates

The phase diagram for a general model for cuprates is derived in a mean-field approximation. A phase-violating time reversal without breaking translational symmetry is possible when both the ionic

Structural and magnetic studies of Sr2IrO4.

The discovery of high-temperature superconductivity in doped copper oxides, which in their insulating forms are nearly ideal two-dimensional spin-1/2 Heisenberg antiferromagnets, has stimulated great

The loop-current order, characterized by the anapole vector Ω, discovered in under-doped cuprates occurs in the same region of the temperature and doping as the pseudo gap observed in STM and ARPES experiments, and the magnitude of theaverage gap systematically increases with the square of the average loop order parameter measured by polarized neutron scattering.

Physics of the Kitaev Model: Fractionalization, Dynamic Correlations, and Material Connections

Quantum spin liquids have fascinated condensed matter physicists for decades because of their unusual properties such as spin fractionalization and long-range entanglement. Unlike conventional
