Topological edge states in curved zigzag superlattices in nonlinear exciton-polaritons
Jing Wang, Tobias Schneider, Wei Hu +2
Zigzag chains allow for the formation of topological edge states. Several distinct chain architectures have been developed for this purpose. Here, we report a zigzag superlattice,…

Transition between self-focusing and self-defocusing in nonlocally nonlinear media
Guo Liang, Weiyi Hong, Yahong Hu +7
We reveal the relevance between the nonlocality and the focusing/defocusing states in nonlocally nonlinear media, and predict a novel phenomenon that the self-focusing/self-defocus…

Observation of Optical Solitons and Abnormal Modulation Instability in Liquid Crystals with Negative Dielectric Anisotropy
Jing Wang, Zhenlei Ma, Junzhu Chen +6
We investigate theoretically and experimentally the optical beam propagation in the nematic liquid crystal with negative dielectric anisotropy, which is aligned homeotropically in…
