Generic model for hyperkagome iridate in the local moment regime
Tomonari Mizoguchi, Kyusung Hwang, Eric Kin-Ho Lee +1
Hyperkagome iridate, NaIrO, has been regarded as a promising candidate material for a three-dimensional quantum spin liquid. Here the three-dimensional network of corne…
X-ray scattering study of pyrochlore iridates: crystal structure, electronic and magnetic excitations
J. P. Clancy, H. Gretarsson, E. K. H. Lee +12
We have investigated the structural, electronic, and magnetic properties of the pyrochlore iridates Eu2Ir2O7 and Pr2Ir2O7 using a combination of resonant elastic x-ray scattering,…
Spin-Orbit Physics Giving Rise to Novel Phases in Correlated Systems: Iridates and Related Materials
Jeffrey G. Rau, Eric Kin-Ho Lee, Hae-Young Kee
Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one of the most actively studied subjects in condensed matter physics, as correlations and SO…
Two iridates, two models, two approaches: a comparative study on magnetism in 3D honeycomb materials
Eric Kin-Ho Lee, Jeffrey G. Rau, Yong Baek Kim
Two recent theoretical works studied the role of Kitaev interactions in the newly observed incommensurate magnetic order in the hyper-honeycomb (-LiIrO) and stripy-honey…
Predominance of the Kitaev interaction in a three-dimensional honeycomb iridate: from ab-initio to spin model
Heung-Sik Kim, Eric Kin-Ho Lee, Yong Baek Kim
The recently discovered three-dimensional hyperhoneycomb iridate, -LiIrO, has raised hopes for the realization of dominant Kitaev interaction between spin-orbit entangle…
Topological spinon semimetals and gapless boundary states in three dimensions
Robert Schaffer, Eric Kin-Ho Lee, Yuan-Ming Lu +1
Recently there has been much effort in understanding topological phases of matter with gapless bulk excitations, which are characterized by topological invariants and protected int…
Theory of Magnetic Phase Diagrams in Hyperhoneycomb and Harmonic-honeycomb Iridates
Eric Kin-Ho Lee, Yong Baek Kim
Motivated by recent experiments, we consider a generic spin model in the basis for the hyperhoneycomb and harmonic-honeycomb iridates. Based on microscopic con…
Topological and magnetic phases with strong spin-orbit coupling on the hyperhoneycomb lattice
Eric Kin-Ho Lee, Subhro Bhattacharjee, Kyusung Hwang +3
We study the general phase diagram of correlated electrons for iridium-based (Ir) compounds on the hyperhoneycomb lattice---a crystal structure where the Ir ions form a thre…
Generic spin model for the honeycomb iridates beyond the Kitaev limit
Jeffrey G. Rau, Eric Kin-Ho Lee, Hae-Young Kee
Recently, realizations of Kitaev physics have been sought in the A2IrO3 family of honeycomb iridates, originating from oxygen-mediated exchange through edge-shared octahedra. Howev…
Order-by-disorder and magnetic field response in Heisenberg-Kitaev model on a hyperhoneycomb lattice
SungBin Lee, Eric Kin-Ho Lee, Arun Paramekanti +1
We study the finite temperature phase diagram of the Heisenberg-Kitaev model on a three dimensional hyperhoneycomb lattice. Using semiclassical analysis and classical Monte-Carlo s…
Heisenberg-Kitaev model on hyperhoneycomb lattice
Eric Kin-Ho Lee, Robert Schaffer, Subhro Bhattacharjee +1
Motivated by recent experiments on LiIrO, we study the phase diagram of the Heisenberg-Kitaev model on a three dimensional lattice of tri-coordinated Ir, dubbed…
Magnetic excitation spectra in pyrochlore iridates
Eric Kin-Ho Lee, Subhro Bhattacharjee, Yong Baek Kim
Metal-insulator transitions in pyrochlore iridates (A2Ir2O7) are believed to occur due to subtle interplay of spin-orbit coupling, geometric frustration, and electron interactions.…
