Tracking doublon-holon dynamics in high-harmonic generation from Mott insulators
Tao-Yuan Du, Hui-Ru Li, Bo Li +1
High-harmonic generation (HHG) in strongly correlated Mott insulators is investigated using exact diagonalization and time-dependent density-matrix propagation of a laser-driven on…
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…
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…
