Author(s): Francesco Di Colandrea, Fabrizio Pavan, Sarvesh Bansal, Paola Savarese, Grazia Di Bello, Giulio De Filippis, Carmine Antonio Perroni, Donato Farina, and Filippo Cardano Non-Hermitian Hamiltonians enrich quantum physics by extending conventional phase diagrams, enabling novel topological phenomena, and realizing exceptional points with applications in quantum sensing. Here, we present a programmable liquid-crystal-based photonic platform for implementing nonunitary … [Phys. Rev. Lett. 137, 126603] Published Tue Sep 15, 2026
