Top panel. Monopole distributions of the lowest magnon band Berry curvature \({{\rm{\Omega }}}_{\mathrm{1,}xz}^{y}(\overrightarrow{k})\) for the photoinduced magnonic WPs at (a) tL/t = 1.5 and (b) tL/t = 3.5. Bottom panel. The thermal Hall conductivity in units of kB. (c) \({\kappa }_{xz}^{y}\) vs. T/t and (d) \({\kappa }_{xy}^{z}\) vs. T/t. Here we set \({{\mathscr{A}}}_{z}={{\mathscr{A}}}_{y}=1.7\), ϕ = π/2, and ω/t = 10.
