Rank-deficient mixed states function as defects that induce an asymptotically robust Uhlmann holonomy on punctured submanifolds, depending only on eigenvalue ratios in an exactly solvable qutrit model.
In a monitored Rashba chain the disconnected entanglement entropy stays topological for a time linear in system size because monitoring switches between degenerate topological states while poisoning other quasiparticles.
