Query: Higher-order topological solitonic insulators   Pursuing topological phase and matter in a variety of systems is one central
issue in current physical sciences and engineering. Motivated by the recent
experimental observation of corner states in acoustic and photonic structures,
we theoretically study the dipolar-coupled gyration motion of magnetic solitons
on the two-dimensional breathing kagome lattice. We calculate the phase diagram
and predict both the Tamm-Shockley edge modes and the second-order corner
states when the ratio between alternate lattice constants is greater than a
critical value. We show that the emerging corner states are topologically
robust against both structure defects and moderate disorders. Micromagnetic
simulations are implemented to verify the theoretical predictions with an
excellent agreement. Our results pave the way for investigating higher-order
topological insulators based on magnetic solitons.
