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…
Non-Bloch edge dynamics of non-Hermitian lattices
Wen-Tan Xue, Fei Song, Yu-Min Hu +1
The non-Hermitian skin effect, i.e., the localization of nominally bulk modes, not only drastically reshapes the spectral properties of non-Hermitian systems, but also dramatically…
Fragile non-Bloch spectrum and unconventional Green's function
Fei Song, Hong-Yi Wang, Zhong Wang
In non-Hermitian systems, it is a counterintuitive feature of the non-Hermitian skin effect (NHSE) that the energy spectrum and eigenstates can be totally different under open or p…
Many-body Liouvillian dynamics with a non-Hermitian tensor-network kernel polynomial algorithm
Guangze Chen, Jose L. Lado, Fei Song
Understanding the dynamics of open quantum many-body systems is a major problem in quantum matter. Specifically, efficiently solving the spectrum of the Liouvillian superoperator g…
Solvable BCS-Hubbard Liouvillians in arbitrary dimensions
Xu-Dong Dai, Fei Song, Zhong Wang
We present the construction of a solvable Lindblad model in arbitrary dimensions, wherein the Liouvillian can be mapped to a BCS-Hubbard model featuring an imaginary interaction. T…
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…
