Query: Zigzag nanoribbons of two-dimensional hexagonal crystals: magnetic,
  topological and thermoelectric properties   Effects of electron-electron and spin-orbit interactions on the ground-state
magnetic configuration and on the corresponding thermoelectric and spin
thermoelectric properties in zigzag nanoribbons of two-dimensional hexagonal
crystals are analyzed theoretically. Thermoelectric properties of quasi-stable
magnetic states are also considered. Of particular interest is the influence of
Coulomb and spin-orbit interactions on the topological edge states and on the
transition between the topological insulator and conventional gap insulator
states. It is shown that the interplay of both interactions has also a
significant impact on transport and thermoelectric characteristics of the
nanoribbons. The spin-orbit interaction additionally determines an in-plane
magnetic easy axis. Thermoelectric properties of the nanoribbons with in-plane
magnetic moments are compared with those of the nanoribbons with edge magnetic
moments oriented perpendicularly to their plane. Nanoribbons with ferromagnetic
alignment of the edge moments are shown to reveal spin thermoelectricity, in
addition to the conventional one.
