Orbital cancellation and reentrant localization in a quasiperiodic trimer ladder
Xin Wang, Pei-Jie Chang, Quanfeng Lu +3
Uniform orbital detuning can restore spatial extent even as quasiperiodic modulation strengthens. In a trimer ladder with fixed hoppings and orbital modulation signs, increasing de…
Global bifurcations and basin geometry of the nonlinear non-Hermitian skin effect
Heng Lin, Yunyao Qi, Gui-Lu Long
We study a continuum Hatano--Nelson model with a saturating nonlinear nonreciprocity and analyze its stationary states via the associated phase-space flow. We uncover a global scen…
Exact Mobility Edges in a Disorder-Free Dimerized Stark Lattice with Effective Unbounded Hopping
Yunyao Qi, Heng Lin, Quanfeng Lu +2
We propose a disorder-free one-dimensional single-particle Hamiltonian hosting an exact mobility edge (ME), placing the system outside the assumptions of no-go theorems regarding u…
Dimer-driven multiple reentrant localization with composite potential
Pei-Jie Chang, Dong Ruan, Gui-Lu Long
Recent studies have revealed reentrant localization transitions in quasi-periodic one-dimensional lattices, where the competition between dimerized hopping and staggered disorder p…
Investigation of reentrant localization transition in one-dimensional quasi-periodic lattice with long-range hopping
Pei-Jie Chang, Qi-Bo Zeng, Jinghui Pi +2
Reentrant localization has recently been observed in systems with quasi-periodic nearest-neighbor hopping, where the interplay between dimerized hopping and staggered disorder is i…
Topological phases of extended Su-Schrieffer-Heeger-Hubbard model
Pei-Jie Chang, Jinghui Pi, Muxi Zheng +3
Despite extensive studies on the one-dimensional Su-Schrieffer-Heeger-Hubbard (SSHH) model, the variant incorporating next-nearest neighbour hopping remains largely unexplored. Her…
Imaginary-Stark Skin Effect
Heng Lin, Jinghui Pi, Yunyao Qi +3
A unique phenomenon in non-Hermitian systems is the non-Hermitian skin effect (NHSE), namely the boundary localization of continuous-spectrum eigenstates. However, studies on the N…
Extended imaginary gauge transformation in a general nonreciprocal lattice
Yunyao Qi, Jinghui Pi, Yuquan Wu +3
Imaginary gauge transformation (IGT) provides a clear understanding of the non-Hermitian skin effect by transforming the non-Hermitian Hamiltonians with real spectra into Hermitian…
