We study the Kitaev-Heisenberg model on the triangular lattice by using the two-dimensional density-matrix renormalization group method. Calculating the ground-state energy and spin structure factors, we obtain the ground state phase diagram of the Kitaev-Heisenberg model. As suggested by previous ...

The Kitaev-Heisenberg (KH) model has been proposed to capture magnetic interactions in iridate Mott insulators on the honeycomb lattice. We show that analogous interactions arise in many other geometries built from edge-sharing IrO6 octahedra, including the pyrochlore and hyperkagome lattices relevant ...

We study the effects of a periodically varying electric field on the Hubbard model at half filling on a triangular lattice. The electric field is incorporated through the phase of the nearest-neighbor hopping amplitude via the Peierls prescription. When the on-site interaction U is much larger ...
Finite-temperature phase transition to a quantum spin liquid in a 3D Kitaev model The Kitaev model has recently attracted considerable attention due to the spin-liquid ground states. This model is defined on a honeycomb lattice, and is exactly solvable due to the Ising conserved quantities associat...
on the role of longer-range Heisenberg interactions, second-neighbor (J2) and third-neighbor (J3), in particular, we performed density-matrix renormalization group (DMRG) calculations33,34 for a J-K-Γ-Γ′-J2-J3 model on fragments of 19, 27, and 37 sites of the triangular lattice. In...
At the same time, the ring exchange coupling is found to drive the system into a state with more short ranged spin correlation and with a local spin correlation pattern equivalent to that of the antiferromagnetic Heisenberg model on triangular lattice(the peak of spin structure factor moves to ...
