Long-Lived Photon Blockade with Weak Optical Nonlinearity
You Wang, Xu Zheng, Timothy C. H. Liew +1
In conventional photon blockade, the occupation of a cavity mode by more than one photon is suppressed via strong optical nonlinearity. An alternative, called unconventional photon…

Noise Constraints for Nonlinear Exceptional Point Sensing
Xu Zheng, Y. D. Chong
Exceptional points (EPs) are singularities in the parameter space of a non-Hermitian system where eigenenergies and eigenstates coincide. They hold promise for enhancing sensing ap…

Deciphering Non-Gaussianity of Diffusion Based on the Evolution of Diffusivity
Haolan Xu, Xu Zheng, Xinghua Shi
Non-Gaussianity indicates complex dynamics related to extreme events or significant outliers. However, the correlation between non-Gaussianity and the dynamics of heterogeneous env…
