Non-Hermitian topology and exceptional-point geometries (2022, neutral): “, |?̅?⟩ = |ψ⟩ √⟨ψ|ψ⟩ , ⟨?̅?| = ⟨ψ| √⟨ψ|ψ⟩ , (8)”
Exceptional topology of non-Hermitian systems (2019, neutral): “…confined to the lower complex half plane, a global shift can make the system effectively PT symmetric in a description, where the less lossy waveguides thus effectively experience gain (Guo et al. , 2009; Feng et al. , 2013; Ornigotti and Szameit, 2014; Weimann et al. , 2017; Kremer et al. , 2019).”

Enhanced sensitivity at higher-order exceptional points (2017, background): “The similarity between equations (4) and (3) demonstrates that the scenario in which the gain and neutral cavities are perturbed is very similar to that in which the perturbation affects the gain cavity only; the only differences are the (1 − 2α)1/3 coefficients.”

Experimental realization of a Weyl exceptional ring (2018, background): “This effect can be viewed as the result of an impedance mismatch between the different sublattices of the system due to the spatially inhomogeneous loss, and can lead to loss-induced transmission in waveguides [67] and reverse pump dependence in lasers [43, 70, 71].”
Dynamically Encircling Exceptional Points: In situ Control of Encircling Loops and the Role of the Starting Point (2018, background): “nvectors coalesce, at EPs both the eigenvalues and the eigenvectors coalesce, leading to various counter-intuitive phenomena and fascinating applications such as loss-induced transmission enhancement [7], lasing effects [8, 9, 10, 11], unusual beam dynamics [12,13], enhanced sensing [14, 15, 16], ro”
