Quasiparticle-continuum level repulsion in a quantum magnet
K. W. Plumb, Kyusung Hwang, Y. Qiu +7
When the energy eigenvalues of two coupled quantum states approach each other in a certain parameter space, their energy levels repel each other and level crossing is avoided. Such…
Emergent quantum phases in a frustrated J1-J2 Heisenberg model on hyperhoneycomb lattice
SungBin Lee, Jae-Seung Jeong, Kyusung Hwang +1
We investigate possible quantum ground states as well as the classical limit of a frustrated J1-J2 Heisenberg model on the three-dimensional (3D) hyperhoneycomb lattice. Our study…
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…
