Thermal and quantum fluctuations in extended Kitaev-Yao-Lee spin-orbital model
Jiefu Cen, Hae-Young Kee
Building upon the spin-1/2 Kitaev model on a honeycomb lattice, the Yao-Lee spin-orbital model provides exactly solvable quantum spin liquids with potentially better stability agai…
Ferrichiral skyrmions with sublattice-resolved chirality in extended Kitaev model in triangular lattice
Bogeng Wen, Jiefu Cen, Hae-Young Kee
We study an extended Kitaev model on the triangular lattice in a limit where the symmetric off-diagonal bond-dependent and Heisenberg interactions together map onto an XXZ model, i…
Spin-orbit coupling controlled two-dimensional magnetism in chromium trihalides
Inhee Lee, Jiefu Cen, Oleksandr Molchanov +7
CrX (X = Cl, Br, I) have the same crystal structure and Hamiltonian but different ligand spin-orbit coupling (SOC) constant , providing excellent material platform explor…
Intermediate phases in -RuCl under in-plane magnetic field via interlayer spin interactions
Jiefu Cen, Hae-Young Kee
-RuCl has attracted significant attention as a prime candidate for the spin-1/2 Kitaev spin liquid in two-dimensional honeycomb lattices. Although its ground state is magne…
