Query: Magnetoelastic coupling enabled tunability of magnon spin current
  generation in 2D antiferromagnets   We theoretically investigate the magnetoelastic coupling (MEC) and its effect
on magnon transport in two-dimensional antiferromagnets with a honeycomb
lattice. MEC coeffcient along with magnetic exchange parameters and spring
constants are computed for monolayers of transition metal trichalcogenides with
N\'eel order ($\text{MnPS}_3$ and $\text{VPS}_3$) and zigzag order
($\text{CrSiTe}_3$, $\text{NiPS}_3$ and $\text{NiPSe}_3$) by $ab$ $initio$
calculations. Using these parameters, we predict that the spin-Nernst
coefficient is significantly enhanced due to magnetoelastic coupling. Our study
shows that although Dzyaloshinskii-Moriya interaction can produce spin Nernst
effect in these materials, other mechanisms such as magnon-phonon coupling
should be taken into account. We also demonstrate that the magnetic anisotropy
is an important factor for control of magnon-phonon hybridization and
enhancement of the Berry curvature and thus the spin-Nernst coefficient. Our
results pave the way towards gate tunable spin current generation in 2D magnets
by SNE via electric field modulation of MEC and anisotropy.
