Quantum Spin Liquid in a Breathing Kagome Lattice
Robert Schaffer, Yejin Huh, Kyusung Hwang +1
Motivated by recent experiments on the vanadium oxyfluoride material DQVOF, we examine possible spin liquid phases on a breathing kagome lattice of S=1/2 spins. By performing a pro…
Theory of Multifarious Quantum Phases and Large Anomalous Hall effect in Pyrochlore Iridate Thin Films
Kyusung Hwang, Yong Baek Kim
We theoretically investigate emergent quantum phases in the thin film geometries of the pyrochore iridates, where a number of exotic quantum ground states are proposed to occur in…
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…
Theory of triplon dynamics in the quantum magnet BiCuPO
Kyusung Hwang, Yong Baek Kim
We provide a theory of triplon dynamics in the valence bond solid ground state of the coupled spin-ladders modelled for BiCuPO. Utilizing the recent high quality neutron sc…
