Observation of Restored Adiabatic State Transfer in Time-Modulated Non-Hermitian Systems
Xiaowei Wang, Ievgen I. Arkhipov, Quan Lin +5
Exceptional points (EPs) have attracted extensive research interest due to their intriguing properties. One of the hallmarks of EP physics is that dynamically encircling the EPs in…
Topological Sensing in the Dynamics of Quantum Walks with Defects
Xiaowei Tong, Xingze Qiu, Xiang Zhan +4
Topological quantum sensing leverages unique topological features to suppress noise and improve the precision of parameter estimation, emerging as a promising tool in both fundamen…
Observation of Metal-Insulator and Spectral Phase Transitions in Aubry-André-Harper Models
Quan Lin, Christopher Cedzich, Qi Zhou +1
Non-Hermitian extensions of the Aubry-André-Harper (AAH) model reveal a rich variety of phase transitions arising from the interplay of quasiperiodicity and non-Hermiticity. Despi…
Simulating Floquet non-Abelian topological insulator with photonic quantum walks
Quan Lin, Tianyu Li, Haiping Hu +2
Floquet non-Abelian topological phases emerge in periodically driven systems and exhibit properties that are absent in their Abelian or static counterparts. Dubbed the Floquet non-…
Experimental device-independent certification of indefinite causal order
Dengke Qu, Quan Lin, Lei Xiao +2
Understanding the physical world fundamentally relies on the assumption that events are temporally ordered, with past events serving as causes for future ones. However, quantum mec…
Non-Hermitian sensing in the absence of exceptional points
Lei Xiao, Yaoming Chu, Quan Lin +4
Open systems possess unique potentials in high-precision sensing, yet the majority of previous studies rely on the spectral singularities known as exceptional points. Here we theor…
