Non-Hermitian Generalization of Rayleigh-Schrödinger Perturbation Theory
Wei-Ming Chen, Yen-Ting Lin, Chia-Yi Ju
While perturbation theories constitute a significant foundation of modern quantum system analysis, extending them from the Hermitian to the non-Hermitian regime remains a non-trivi…

Evidence for Exceptional Points as Topological Defects
Chia-Yi Ju, Szu-Ming Chen
Studies have shown that quantum states reside in a Hilbert space bundle. When a quantum system depends on continuous external parameters, these parameters define additional dimensi…

Quantum State Evolution and Berry Potentials at Exceptional Points and Quantum Phase Transitions
Chia-Yi Ju, Fu-Hsiang Huang
The behavior of quantum states at exceptional points and at critical points associated with quantum phase transitions is intriguing yet puzzling. In this study, we present an alter…
