Logarithmically Correlated Landscapes and Localization in Non-Hermitian Quasicrystals
Xianqi Tong, Qifeng Ding, Xiaosen Yang
We study a one-dimensional Hatano-Nelson ring whose nonreciprocal hopping is quasiperiodically modulated through zero. A gauge transformation maps every eigenstate onto a single sp…
Analytical mobility edge in nonreciprocal quasiperiodic lattices with next-nearest-neighbor hopping
Wenmin Wang, Xiaosen Yang, Xianqi Tong
The paper derives an analytical expression for the energy-dependent mobility edge in a non‑Hermitian, nonreciprocal extension of the Aubry‑André quasiperiodic lattice, showing how…
Interplay of Quasiperiodic Criticality and the Non-Hermitian Skin Effect
Zhangyuan Chen, Xianqi Tong, Xiaosen Yang
Quasiperiodic lattices can host critical eigenstates, whereas nonreciprocal hopping in non-Hermitian lattices can induce non-Hermitian skin effect. In this work, we investigate loc…
Non-Hermitian Mosaic Maryland model
Zhenning Wang, Ni Lu, Dan Liu +2
We introduce the non-Hermitian mosaic Maryland model, where a discrete modulation period and a non-Hermitian phase are incorporated into the potential, rendering the originally exa…
Quasiperiodic Skin Criticality in an Exactly Solvable Non-Hermitian Quasicrystal
Zhangyuan Chen, Muhammad Idrees, Ying Yang +2
Critical states in quasiperiodic systems defy the conventional dichotomy between extended and localized states. In this work, we demonstrate that non-Hermiticity fundamentally resh…
Impact of Nonreciprocal Hopping on Localization in Non-Hermitian Quasiperiodic Systems
Xianqi Tong, Yiling Zhang, Bin Li +1
We study the non-Hermitian Aubry-André-Harper model, incorporating complex phase modulation, unmodulated and modulated nonreciprocal hopping. Using Avila's global theory, we deriv…
