Skin effects in non-Hermitian Luttinger liquids fractionalize by symmetry, producing decoupled spin and charge skin modes at low energies plus an interaction-enabled E8 skin effect absent in free fermions.
Non-Hermiticity induces fractional topological phases in nonlinear Thouless pumping of a Rice-Mele model, explained through auxiliary eigenvalue equations that connect nonlinear spectra to bulk-boundary correspondence.
A review summarizing theoretical and experimental progress on disorder-induced topological phases including TAIs, quasiperiodic extensions, non-Hermitian systems, and many-body realizations.
