Mobile-impurity dynamics in a non-Hermitian Stark-localised bath
Muhammad S. Hasan, Hsiang-Hua Jen, Jhih-Shih You
We investigate the dynamics of a clean mobile impurity coupled to a bath subjected to a linear Stark potential as well as asymmetric hopping in one dimension. The impurity mediates…
Exceptional Topology Survives Strong Hermitian Fields in Radiative Atomic Arrays
Tian-Shu Gou, Yi-Cheng Wang, Ya-Tang Yu +3
Exceptional points are topological defects of complex band structures that are stable against weak perturbations, yet in two-band systems with bounded non-Hermitian couplings they…
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…
