Layer-Locked Chiral Topological Superconductivity
Yijie Mo, Zhongbo Yan
We uncover a universal mechanism for realizing layer-locked topological phases. Guided by it, we investigate the realization of layer-locked chiral topological superconductivity-th…
Theory for the spectral splitting exponent of exceptional points
Shu-Xuan Wang, Zhongbo Yan
Exceptional points (EPs), singularities in non-Hermitian systems where eigenvalues and eigenstates coalesce, exhibit a dramatically enhanced response to perturbations compared to H…
Coexistence of Chiral Majorana Edge States and Bogoliubov Fermi Surfaces in Two-Dimensional Nonsymmorphic Dirac Semimetal/Superconductor Heterostructures
Yijie Mo, Xiao-Jiao Wang, Zheng-Yang Zhuang +1
Dirac semimetals are renowned for the host of singular symmetry-protected band degeneracies which can give rise to other exotic phases. In this work, we consider a two-dimensional…
Field-sensitive dislocation bound states in two-dimensional -wave altermagnets
Di Zhu, Dongling Liu, Zheng-Yang Zhuang +2
When a two-dimensional -wave altermagnet is grown on a substrate, the interplay of momentum-dependent spin splittings arising from altermagnetism and Rashba spin-orbit coupling…
Uniaxial stress tuning of interfacial thermal conductance in cubic BAs/4H-SiC heterostructures
Lei Zhang, Fei Tian, Ke Chen +2
Understanding interfacial thermal transport is essential for improving thermal management in high-speed power electronic devices, where the efficient removal of excess heat is a cr…
Super-enhanced Sensitivity in Non-Hermitian Systems at Infernal Points
Shu-Xuan Wang, Zhongbo Yan
The emergence of exceptional points in non-Hermitian systems represents an intriguing phenomenon characterized by the coalescence of eigenenergies and eigenstates. When a system ap…
