Query: Hexagon Ising-Kondo lattice: An implication for intrinsic
  antiferromagnetic topological insulator   Recently, the MnBi$_2$Te$_4$ material has been proposed as the first
intrinsic antiferromagnetic topological insulator (AFMTI), where the interplay
between magnetism and topology induces several fascinating topological phases,
such as the quantum anomalous Hall effect, Majorana fermions, and axion
electrodynamics. However, an exactly solvable model being capable to capture
the essential physics of the interplay between magnetism and topology is still
absent. Here, inspired by the the Ising-like nature [B. Li \textit{et al.}
Phys. Rev. Lett. \textbf{124}, 167204 (2020)] and the topological property of
MnBi$_2$Te$_4$, we propose a topological Ising-Kondo lattice (TIKL) model to
study its ground state property in an analytical way at zero temperature. The
resultant phase diagram includes rich topological and magnetic states, which
emerge in the model proposed in a natural and consistent way for the intrinsic
magnetic topological insulator. With Monte Carlo simulation, we extend the
AFMTI ground state to finite temperature. It reveals that topological
properties do sustain at high temperature, which even can be restored by
elevated temperature at suitable correlation strength. The results demonstrate
that TIKL may offer an insight for future experimental research, with which
magnetism and transport properties could be fine tuned to achieve more stable
and exotic magnetic topological quantum states.
