Emergence of Triplet Superconductivity from Cavity Vacuum Fluctuations
Xin-Xin Yang, Shuai Zhang, Kun Ding +1
Engineering quantum materials with cavity fields has emerged as a powerful route to manipulate phases of quantum matter in solids. Here we demonstrate that cavity vacuum fluctuatio…
Geometry-induced Exceptional Point Detached from Fermi Arcs
Yuancheng Zhao, Jia-Xin Zhong, Jing Lin +2
Exceptional points (EPs), ubiquitous non-Hermitian degeneracies, are central features in band structures where non-Hermitian Fermi arcs connect EPs and eigenvalue knots encircle th…
Unveiling non-Hermitian band structures with non-Bloch supercells
Jia-Xin Zhong, Jing Lin, Kai Chen +3
Real-valued band structures are foundational to analyzing periodic systems within the Hermitian description and have been experimentally well-established over recent decades. In co…
Algebraic skin effect in two-dimensional non-Hermitian metamaterials
Mingyang Li, Jing Lin, Kun Ding
Metamaterials have unlocked unprecedented control over light by leveraging novel mechanisms to expand their functionality. Non-Hermitian physics further enhances the tunability of…
Experimentally Probing Non-Hermitian Spectral Transition and Eigenstate Skewness
Jia-Xin Zhong, Jeewoo Kim, Kai Chen +3
Non-Hermitian (NH) systems exhibit intricate spectral topology arising from complex-valued eigenenergies, with positive/negative imaginary parts representing gain/loss. Unlike the…
