Query: Photoinduced topologically trivial magnons with finite thermal Hall
  effect   In two-dimensional (2D) insulating magnets, the thermal Hall effect of
magnons is believed to be a consequence of topological magnon insulator with
separated magnon bands and a well-defined Chern number. Due to broken
time-reversal symmetry the thermal Hall effect vanishes in Dirac magnons. In
this paper, we show that periodically driven semi-Dirac magnon in 2D insulating
honeycomb ferromagnet results in a photoinduced Dirac magnon at the topological
phase transition between a photoinduced topological and trivial magnon
insulator. Remarkably, the photoinduced Dirac magnon and the photoinduced
trivial magnon insulator possess a nonzero Berry curvature and exhibit a finite
thermal Hall effect. These intriguing properties of periodically driven 2D
insulating magnets originate from the bosonic nature of magnons. Hence, they
are not expected to exist in 2D electronic Floquet systems.
