Metal-Insulator Coexistence and Gap-Crossing Domain-Wall Modes in an Aubry-André Model with Nonlocal Hopping
Xiarui Zhan, Mingsheng Tian, Qiongyi He +2
Nonequilibrium transport remains a central theme in modern physics, spanning from condensed matter to synthetic systems. Here, we investigate particle transport in an extended Aubr…

From Spectral Singularities to Multipartite Entanglement Scaling at Higher-Order Exceptional Points
Chunlai Yang, Shuheng Liu, Xinyao Huang +2
Exceptional points (EPs) are non-Hermitian spectral singularities exhibiting fractional-power responses, yet their implications for multipartite entanglement of interacting quantum…
