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…

Scale-free localization and PT symmetry breaking from local non-Hermiticity
Bo Li, He-Ran Wang, Fei Song +1
We show that a local non-Hermitian perturbation in a Hermitian lattice system generically induces scale-free localization for the continuous-spectrum eigenstates. When the perturba…

Scale-free non-Hermitian skin effect in a boundary-dissipated spin chain
He-Ran Wang, Bo Li, Fei Song +1
We study the open XXZ spin chain with a PT-symmetric non-Hermitian boundary field. We find an interaction-induced scale-free non-Hermitian skin effect by using the coordinate Bethe…
