A particle worldline in E8 exceptional field theory is made gauge-invariant by adding a coadjoint-orbit "duality charge", and the same Hamiltonian framework organizes exotic zero-brane dynamics such as the 0^(1,7) brane.
Generalizes the BIZZ recursive procedure and provides sufficient conditions under which auxiliary field deformations of integrable sigma models retain classical Yangian symmetry and Maillet bracket structure.
Derives integrable deformations of the BM sigma model from 4d Chern-Simons theory via Cole-Weck model deformations linked to homogeneous and inhomogeneous classical Yang-Baxter equations.
