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…
Accelerating multipartite entanglement generation in non-Hermitian superconducting qubits
Chimdessa Gashu Feyisa, J. S. You, Huan-Yu Ku +1
Open quantum systems are susceptible to losses in information, energy, and particles due to their surrounding environment. One novel strategy to mitigate these losses is to transfo…
