Boundary-sensitive non-Hermiticity of Floquet Hamiltonian: spectral transition and scale-free localization
Bo Li, He-Ran Wang, Fei Song
We report a novel mechanism of boundary-sensitive PT symmetry breaking in one-dimensional Floquet systems. By designing a time-periodic driving protocol, we realize a Floquet Hamil…

Universal non-Hermitian transport in disordered systems
Bo Li, Chuan Chen, Zhong Wang
In disordered Hermitian systems, localization of energy eigenstates prohibits wave propagation. In non-Hermitian systems, however, wave propagation is possible even when the eigens…

Non-Bloch dynamics and topology in a classical non-equilibrium process
Bo Li, He-Ran Wang, Fei Song +1
The non-Hermitian skin effect refers to the accumulation of eigenstates near the boundary in open boundary lattice models, which can be systematically characterized using the non-B…
