Two kinds of phase transition in photonic systems with application to optical isolation by Zhou, Xin

“…We study three representative designs: (i) a waveguide array implementing a nonlinear 1D Su-Schrieffer-Heeger model, (ii) a waveguide array implementing a nonlinear 2D Haldane model, and (iii) a 2D lattice of coupled-ring waveguides. In the first two cases, we find a correspondence between the topological transition of the underlying linear lattice and the power threshold of the transmittance, and show that the transmission behavior is attributable to the emergence of a self-induced topological soliton. …”

The burden of consciousness : object animism in children's literature by Yam, Hui Qing

“…Animals, plants and objects are often anthropomorphized to delightful effect in children’s literature while adult depictions of the inanimate coming alive almost always occur in the genres of science fiction and horror and have had a much less positive spin. This essay argues that these negative evocations do indeed spill over into children’s texts, manifesting in the common motifs that appear in stories involving object animism, and that enlivened objects are furthermore, representations of Julia Kristeva’s concept of abjection.…”
