Author(s): Markus Bestler, Alexander Dikopoltsev, and Oded Zilberberg This theoretical study demonstrates that Hermitian, momentum-shifted parametric pairing processes can induce non-Hermitian topology and skin modes in bosonic continuum systems. Stabilized by local dissipation, the model exhibits exceptional points, a non-Hermitian Fermi arc, and a robust bulk-boundary correspondence. [Phys. Rev.
