Rashba Spin-Orbit Driven Topological Phase Transitions in Heterogeneous Armchair Honeycomb Nanoribbons
Hao-Ru Wu, Jhih-Shih You, Yiing-Rei Chen +1
We investigate the emergence of nontrivial topological phases in heterogeneous armchair honeycomb nanoribbons arising from the interplay between structural geometry and Rashba spin…

Scaling of Quantum Geometry Near the Non-Hermitian Topological Phase Transitions
Y R Kartik, Jhih-Shih You, H. H. Jen
The geometry of quantum states can be an indicator of criticality, yet it remains less explored under non-Hermitian topological conditions. In this work, we unveil diverse scalings…

Robustness of tripartite entangled states in passive PT-symmetric qubits
C. G. Feyisa, Cheng-Yu Liu, Muhammad S. Hasan +3
Non-Hermitian quantum systems have attracted significant interest in recent years due to the presence of unique spectral singularities known as exceptional points (EPs), where eige…
