Topological superconductivity in layered d-wave altermagnetic metals
Yijie Mo, Zhongbo Yan
We investigate multilayer d-wave altermagnetic metals with odd-parity helical p-wave pairing. In the minimal bilayer system, interlayer tunneling reconstructs the spin-split Fermi…

Non-Hermitian skin effect is one of the most captivating phenomena in non-Hermitian systems, characterized by the extensive localization of eigenstates near open boundaries. In its…
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…
