- Abstract summary: Strain engineering is a powerful tool which may facilitate the experimental realization and control of topological phases in laser-driven 2D ferromagnetic systems.
We show that by applying a circularly polarized laser field to a 2D honeycomb ferromagnet which is uniaxially strained in either the zig-zag or armchair direction, it is possible to generate a synthetic Dzyaloshinskii-Moriya interaction (DMI) tunable by the intensity of the applied electric field.

- Abstract: We argue that strain engineering is a powerful tool which may facilitate the
experimental realization and control of topological phases in laser-driven 2D
ferromagnetic systems. To this extent, we show that by applying a circularly
polarized laser field to a 2D honeycomb ferromagnet which is uniaxially
strained in either the zig-zag or armchair direction, it is possible to
generate a synthetic Dzyaloshinskii-Moriya interaction (DMI) tunable by the
intensity of the applied electric field, as well as by the magnitude of applied
strain. Such deformations enable transitions to phases with opposite sign of
Chern number, or to trivial phases. These are basic results that could pave the
way for the development of a new field of Strain Engineered Topological
Spintronics (SETS).

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

High-order topological insulator (HOTI) occupies an important position in topological band theory.
Recently, it has been predicted that external magnetic field can introduce rich physics into 2D HOTIs.
