Emergent Spin Hall Quantization and High‐Order van Hove singularities in Square‐Octagonal MA2Z4

open access: yesAdvanced Physics Research, EarlyView.
Square‐octagonal MA2Z4 (M = Mo/W, A = Si/Ge, Z = pnictogen) monolayers are predicted to realize quantum spin Hall insulators with nearly quantized spin Hall conductivity enabled by an emergent spin U(1) quasi‐symmetry. Materials with Z = As and Sb host quasi‐flat bands with high‐order van Hove singularities near the Fermi level, making them promising ...

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

open access: yesAdvanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Sensitivity enhancement of a bimetallic surface plasmon resonance biosensor

open access: yesJournal of Optoelectronical Nanostructures
In this study, a plasmonic biosensor with a kreschmann configuration is evaluated by changing the sensing medium's refractive index from 1.330 to 1.335, which includes BK7, gold/silver, silicon, nickel, hexagonal boron nitride, black phosphorus ...
