Electrons driven by chiral phonons contribute to nonzero topological orbital magnetization expressed as a second Chern form.

Topological electrons generate an effective magnetic field--expressed as molecular Berry curvature--on phonon dynamics, leading to optical phonons with circular polarization.

Spontaneous phonon chirality driven by linearly polarized light in the presence of nonlinear spin-phonon coupling.

Applying an in-plane exchange field can gap out the edge states of Z2 topological insulator and generate corner states and higher-order band topology.
