A scale-free topological directional amplification is found in the Hatano-Nelson model with perturbed open boundaries, attributed to first-order boundary effects and characterized by a winding number on a continuous generalization of the finite-size Brillouin zone.

Scale-Free Response with Directional Amplification in Critical Non-Hermitian Systems
A scale-free topological directional amplification is found in the Hatano-Nelson model with perturbed open boundaries, attributed to first-order boundary effects and characterized by a winding number on a continuous generalization of the finite-size Brillouin zone.
