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.
Postselection on continuous monitoring of spontaneous emission slows entanglement decay in a two-transmon system and reveals exceptional points with PT-symmetric phases in the interaction frame.
