The Edge of Order: How Quasiperiodicity Shatters Localization
![The system exhibits tunable, non-reciprocal hopping-characterized by strengths of [latex]J e^{\pm\alpha}[/latex]-coupled with a quasiperiodic onsite potential [latex]\lambda_{j}[/latex], and further refined by an impurity bond whose hopping strength is adjustable via parameter μ.](https://arxiv.org/html/2602.11155v1/x1.png)
New research reveals how introducing quasiperiodic order into non-Hermitian systems can dramatically alter electron behavior, leading to either extended states or the emergence of the non-Hermitian skin effect.
