Black-Hole Ringdown from Photon-Sphere Modes in an Elastic Analogue
Jiaoqing Wang, Chenni Xu, Sophia Purow +2
Quasinormal modes (QNMs) govern the ringdown of black holes, yet their physical origin and experimental accessibility remain limited. Here we create an elastic analogue of a black…

The Spontaneous Cascading Mechanism Behind Critical Phenomena in Self-Coupled Lasers
Jiaoqing Wang, Yael Kfir-Cohen, Chenni Xu +4
The basic physics of lasers is characterized by a second-order continuous phase transition at the critical lasing threshold. Nevertheless, laser bistability with abrupt transitions…
