Recently, realizations of Kitaev physics have been sought in the A 2 IrO 3 family of
honeycomb iridates, originating from oxygen-mediated exchange through edge-shared …

Intensive studies of the interplay between spin-orbit coupling (SOC) and electronic
correlations in transition-metal compounds have recently been undertaken. In particular, j …

Extending the notion of symmetry protected topological phases to insulating
antiferromagnets (AFs) described in terms of opposite magnetic dipole moments associated …

Motivated by recent experiments, we consider a generic spin model in the j eff= 1/2 basis for
the hyperhoneycomb and harmonic-honeycomb iridates. Based on microscopic …

Topological Kondo insulators are a new class of topological insulators in which metallic
surface states protected by topological invariants reside in the bulk band gap at low …

Iridium oxides with a honeycomb lattice have been identified as platforms for the much
anticipated Kitaev topological spin liquid: the spin-orbit entangled states of Ir4+ in principle …

Measurements of the London penetration depth Δ λ (T) and tunneling conductance in single
crystals of the recently discovered stoichiometric iron-based superconductor CaKFe 4 As 4 …

We synthesize and study single crystals of the layered honeycomb lattice Mott insulators Na
2 RuO 3 and Li 2 RuO 3 with magnetic Ru 4+(4 d 4) ions. The newly found Na 2 RuO 3 …

We report the successful synthesis of single crystals of the layered iridate (Na 1− x Li x) 2 IrO
3, 0≤ x≤ 0.9, and a thorough study of its structural, magnetic, thermal, and transport …

The ability to fine-tune band gap and band inversion in topological materials is highly
desirable for the development of novel functional devices. Here we propose that the …
