We explore the phase diagram of the strongly correlated Hubbard model with intrinsic spin orbit coupling on the honeycomb lattice. We obtain the low energy effective model describing the spin degree of freedom. We study the resulting model within the Schwinger boson and Schwinger fermion approaches. The Schwinger boson approach gives the boundary between the spin liquid phase and the magnetically ordered phases, Neel order and incommensurate Neel order. We find that increasing the strength of… Expand

Phase transitions of the Kane-Mele-Hubbard model with a long-range hopping.
From the single-particle energy spectrum, the critical strength of the long-range hopping t L at which the topological transition occurs in the non-interacting limit of the model is obtained and results show that it is independent of the spin-orbit coupling. Expand
Topological insulators present a bulk gap, but allow for dissipationless spin transport along the edges. These exotic states are characterized by the Z2 topological invariant and are protected byExpand
Axionic Antiferromagnetic Insulator Phase in a Correlated and Spin–Orbit Coupled System
We study theoretically a three-dimensional correlated and spin–orbit coupled system, the half-filled extended Fu–Kane–Mele–Hubbard model on a diamond lattice, focusing on the topologicalExpand
Antiferromagnetic Chern Insulators in Noncentrosymmetric Systems.
An easy z axis C=1 AFCI phase and a spin-flop transition to a topologically trivial xy plane collinear antiferromagnet is found and proposed experimental realizations of the AFCI and QAHE in correlated electron materials and cold atom systems are proposed. Expand
Ultrafast control of spin interactions in honeycomb antiferromagnetic insulators
Light enables ultrafast, direct and nonthermal control of the exchange and Dzyaloshinskii-Moriya interactions. We consider two-dimensional honeycomb lattices described by the Kane-Mele-Hubbard modelExpand
Phase diagram of a frustrated Heisenberg antiferromagnet on the honeycomb lattice: The J 1-J 2-J 3 model
We use the coupled-cluster method in high orders of approximation to make a comprehensive study of the ground-state (GS) phase diagram of the spin-1/2 J1-J2-J3 model on a two-dimensional honeycombExpand
Valence bond phases in S = 1/2 Kane-Mele-Heisenberg model.
The phase diagram of the Kane-Mele-Heisenberg model in a classical limit [47] contains disordered regions in the coupling space, as the result of competition between different terms in theExpand
The competition between the intrinsic and Rashba spin-orbit coupling and effects of correlations on Rashba SOC-driven transitions in the Kane-Mele model.
The competition between the Rashba spin-orbit coupling (SOC) and the intrinsic SOC in Kane-Mele model is investigated and the influences of the correlation on the RashBA SOC-driven topologically trivial and non-trivial transitions in both the charge condensate and Mott regions are investigated.

Magnetic Chern Insulators in a monolayer of Transition Metal Trichalcogenides
It is shown that the interplay of intrinsic spin-orbit coupling and electron correlation opens a wide region of ferromagnetic Chern insulating phases in between metals and normal insulators. Expand
