Roadmap on topological photonics (2022, neutral): “In order to resolve all the different localised bulk modes of the non-Hermitian SSH circuit, impedance measurements were taken in a range to extend over more than six orders of magnitude [111].”
Probing non-Hermitian skin effect and non-Bloch phase transitions (2019, background): “These models, originally introduced mostly as theoretical models, are nowadays being experimentally accessible with synthetic topological matter using photonic structures and topolectrical circuits [37, 51, 53, 54, 57].”
Entanglement Phase Transition Induced by the Non-Hermitian Skin Effect (2022, background): “The skin effect has recently been observed in classical experiments of mechanical metamaterials [123], electrical circuits [124, 125], photonic lattices [126], and active particles [127], as well as quantum experiments of single photons [128] and ultracold atoms [129].”
Topological dissipation in a time-multiplexed photonic resonator network (2021, neutral): “Immediate extensions of our current experiments include exploring non-Hermitian 53,54 and nonlinear 55 topological behaviours in dissipatively coupled time-multiplexed networks.”
Exceptional topology of non-Hermitian systems (2019, positive): “…et al. , 2015; Zeuner et al. , 2015; Chen et al. , 2017; Hodaei et al. , 2017; Weimann et al. , 2017; Bandres et al. , 2018; Zhou et al. , 2018; Cerjan et al. , 2019; Helbig et al. , 2020), extending the notion of topological phases to NH systems has become a broad frontier of current research.”
Perspective on topological states of non-Hermitian lattices (2019, background): “We note that, after submission of this article, different experiments have put forward realizations of this anomalous localization in topoelectrical circuits [106, 107], quantumwalks [108]mechanical systems [109] andmagnons [110].”
Topological active matter (2020, background): “Recent studies have also suggested a role for topological states in nonequilibrium stochastic [216], excitable [217–220], and evolutionary dynamics [221] networks.”
A review on non-Hermitian skin effect (2022, methodology): “By using electric circuits, the NHSE has been demonstrated not only in 1D systems [130,131,133], but also in two and higher dimensions where hybrid higher-order skin-topological modes and second-order NHSE designed by unsupervised physics-graph-informed machine learning were experimentally observed ”
