Relevance of the Heisenberg-Kitaev model for the honeycomb lattice iridates A_2IrO_3
Yogesh Singh, S. Manni, J. Reuther +5
Combining thermodynamic measurements with theoretical density functional and thermodynamic calculations we demonstrate that the honeycomb lattice iridates A2IrO3 (A = Na, Li) are m…
Finite-temperature phase diagram of the Heisenberg-Kitaev model
Johannes Reuther, Ronny Thomale, Simon Trebst
We discuss the finite-temperature phase diagram of the Heisenberg-Kitaev model on the hexagonal lattice, which has been suggested to describe the spin-orbital exchange of the effec…
Magnetic order and paramagnetic phases in the quantum J1-J2-J3 honeycomb model
Johannes Reuther, Dmitry Abanin, Ronny Thomale
Recent work shows that a quantum spin liquid can arise in realistic fermionic models on a honeycomb lattice. We study the quantum spin-1/2 Heisenberg honeycomb model, considering c…
