Light-Induced Even-Wave Spin Splittings in Nonmagnetic Centrosymmetric Systems with Spin-Orbit Coupling
Xiao-Jiao Wang, Dongling Liu, Di Zhu +2
Spin splitting underpins a vast range of spin-dependent phenomena. Traditionally, two primary mechanisms generate such splitting: relativistic spin-orbit coupling (SOC) and nonrela…
Intrinsic Second-Order Topological Superconductors with Tunable Majorana Zero Modes
Xiao-Jiao Wang, Yijie Mo, Zhi Wang +2
Dirac semimetals, with their protected Dirac points, present an ideal platform for realizing intrinsic topological superconductivity. In this work, we investigate superconductivity…
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…
Topological superconductivity in two-dimensional -junction Dirac semimetals
Yijie Mo, Xiao-Jiao Wang, Zhongbo Yan
Odd-parity pairings offer a natural pathway for realizing topological superconductivity. When two identical even-parity superconductors form a -junction, the metallic material…
Boundary Flat Bands with Topological Spin Textures Protected by Sub-chiral Symmetry
Yijie Mo, Xiao-Jiao Wang, Rui Yu +1
Chiral symmetry plays an indispensable role in topological classifications as well as in the understanding of the origin of bulk or boundary flat bands. The conventional definition…
Berry-dipole Semimetals
Zheng-Yang Zhuang, Chaoyi Zhang, Xiao-Jiao Wang +1
We introduce ''Berry-dipole semimetals'', whose band degeneracies are characterized by quantized Berry dipoles. Through a two-band model constructed by Hopf map, we reveal that the…
