  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>Topological states
    have been widely investigated in different types of systems and lattices. 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>"

  text: "<jats:p>Exceptional points (EPs), with their intriguing spectral topology,
    have attracted considerable attention in a broad range of physical systems, with
    potential sensing applications driving much of the present research in this field.
    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
