Critical Topological Photonics in Synthetic Dimensions
Mingyuan Chen, Yuwei Jing, Franco Nori +1
Topological states and criticality have long been regarded as incompatible ingredients: the former requires a finite spectral gap, whereas the latter demands its closure. Guided by…

Exceptional-point-like Sensing near Hermitian Critical Points
Jiang-Shan Tang, Long-Qi Xiao, Hao-Dong Wu +6
A non-Hermitian system at an exceptional point (EP), a specific critical point (CP) associated with the parity-time symmetric phase transition, exhibits a sublinear response to per…
