Non-Fermi liquid and topological states with strong spin-orbit coupling
Eun-Gook Moon, Cenke Xu, Yong Baek Kim +1
We argue that a class of strongly spin-orbit coupled materials, including some pyrochlore iridates and the inverted band gap semiconductor HgTe, may be described by a minimal model…
Three-dimensional nematic spin liquid in the stacked triangular lattice 6H-B structure
Kyusung Hwang, Tyler Dodds, Subhro Bhattacharjee +1
Recently, a number of experiments indicate the possible presence of spin liquid phases in quantum magnets with spin-1/2 and spin-1 moments sitting on triangular-lattice-based struc…
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.…
Pyrochlore electrons under pressure, heat and field: shedding light on the iridates
William Witczak-Krempa, Ara Go, Yong Baek Kim
We study the finite temperature and magnetic field phase diagram of electrons on the pyrochlore lattice subject to a local repulsion as a model for the pyrochlore iridates. We prov…
Influence of Dzyaloshinskii-Moriya interactions on magnetic structure of a spin-1/2 deformed kagome lattice antiferromagnet
Kyusung Hwang, Kwon Park, Yong Baek Kim
Motivated by the recent neutron scattering experiment on Rb2Cu3SnF12 [Nat. Phys. 6, 865 (2010)], we investigate the effect of Dzyaloshinskii-Moriya interactions in a theoretical mo…
Quantum Phase Transition in Heisenberg-Kitaev Model
Robert Schaffer, Subhro Bhattacharjee, Yong Baek Kim
We explore the nature of the quantum phase transition between a magnetically ordered state with collinear spin pattern and a gapless spin liquid in the Heisenberg-Kitaev mode…
