Result description
This study analyzes how exceptional points and non-Hermitian spectral features shape the evolution of a periodically driven open quantum system. It reveals how coherence loss and state localization change with system parameters, drawing analogies to phenomena like the skin effect. The findings deepen our understanding of dissipative Floquet systems and highlight structural links between symmetry, dynamics, and decoherence in open quantum physics.
We explore the dynamics of a periodically driven two-level system under the Lindblad equation, revealing how exceptional points induce rapid dephasing and coherence loss. Using adiabatic, numerical, and Floquet methods, we uncover connections to Lie algebra structure and non-Hermitian phenomena, including a transition from Wannier-Stark ladders to skin-effect-like sensitivity. This work contributes to the understanding of open quantum systems in memory of Göran Lindblad and targets researchers in non-Hermitian dynamics, quantum dissipation, and Floquet engineering.
