In the present work, we report on topological edge states in double-wave (DW) chains, which can be described by a generalized Aubry-André-Harper (AAH) model. For the specific system of a driven-dissipative exciton polariton system we show that in such potential chains, different types of edge states can form. For resonant optical excitation, we further find that the optical nonlinearity leads to a multistability of different edge states. This includes topologically protected edge states evolved directly from individual linear eigenstates as well as additional edge states that originate from nonlinearity-induced localization of bulk states. Extending the system into two dimensions (2D) by stacking horizontal DW chains in the vertical direction, we also create 2D multi-wave lattices. In such 2D lattices multiple Su–Schrieffer–Heeger (SSH) chains appear along the vertical direction. The combination of DW chains in the horizonal and SSH chains in the vertical direction then results in the formation of higher-order topological insulator corner states. Multistable corner states emerge in the nonlinear regime.</jats:p>"}],"date_created":"2025-09-12T11:19:22Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"type":"journal_article","status":"public","publisher":"Walter de Gruyter GmbH","_id":"61255","page":"509-518","volume":13,"user_id":"16199","citation":{"mla":"Schneider, Tobias, et al. “Topological Edge and Corner States in Coupled Wave Lattices in Nonlinear Polariton Condensates.” <i>Nanophotonics</i>, vol. 13, no. 4, Walter de Gruyter GmbH, 2024, pp. 509–18, doi:<a href=\"https://doi.org/10.1515/nanoph-2023-0556\">10.1515/nanoph-2023-0556</a>.","ama":"Schneider T, Gao W, Zentgraf T, Schumacher S, Ma X.

Here, we investigate spectral topology and EPs in systems with significant nonlinearity, exemplified by a nonequilibrium exciton-polariton condensate. With the possibility to control loss and gain and nonlinearity by optical means, this system allows for a comprehensive analysis of the interplay of nonlinearities (Kerr type and saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally shifted in parameter space by the saturable gain, but we also observe intriguing rotations and intersections of Riemann surfaces and find nonlinearity-enhanced sensing capabilities. With this, our results illustrate the potential of tailoring spectral topology and related phenomena in non-Hermitian systems by nonlinearity.</jats:p>\r\n          <jats:sec>\r\n            <jats:title/>\r\n            <jats:supplementary-material>\r\n              <jats:permissions>\r\n                <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement>\r\n                <jats:copyright-year>2024</jats:copyright-year>\r\n              </jats:permissions>\r\n            </jats:supplementary-material>\r\n          </jats:sec>"}],"issue":"1","publication":"Physical Review Research","type":"journal_article","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"35"},{"_id":"230"},{"_id":"27"},{"_id":"429"}],"date_created":"2025-09-12T11:23:33Z","date_updated":"2025-09-12T11:24:59Z","publication_status":"published","intvolume":"         6","year":"2024","title":"Manipulating spectral topology and exceptional points by nonlinearity in non-Hermitian polariton systems","publication_identifier":{"issn":["2643-1564"]},"author":[{"first_name":"Jan","last_name":"Wingenbach","full_name":"Wingenbach, Jan","id":"69187"},{"full_name":"Schumacher, Stefan","last_name":"Schumacher","first_name":"Stefan","orcid":"0000-0003-4042-4951","id":"27271"},{"first_name":"Xuekai","last_name":"Ma","full_name":"Ma, Xuekai","id":"59416"}],"doi":"10.1103/physrevresearch.6.013148","article_number":"013148","language":[{"iso":"eng"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"},{"_id":"54","name":"TRR 142 - Project Area A"},{"_id":"61","name":"TRR 142; TP A04: Nichtlineare Quantenprozesstomographie und Photonik mit Polaritonen in Mikrokavitäten"}],"citation":{"bibtex":"@article{Wingenbach_Schumacher_Ma_2024, title={Manipulating spectral topology and exceptional points by nonlinearity in non-Hermitian polariton systems}, volume={6}, DOI={<a href=\"https://doi.org/10.1103/physrevresearch.6.013148\">10.1103/physrevresearch.6.013148</a>}, number={1013148}, journal={Physical Review Research}, publisher={American Physical Society (APS)}, author={Wingenbach, Jan and Schumacher, Stefan and Ma, Xuekai}, year={2024} }","ama":"Wingenbach J, Schumacher S, Ma X.
