Pinning of a High-Energy Wavepacket by a Single Impurity
Fartash Chalangari, Anant Vijay Varma, Joonas Keski-Rahkonen +1
We demonstrate that a single repulsive impurity enhances directional confinement of a high-energy wavepacket in a finite two-dimensional lattice of quantum wells. At energies far a…

Coexistence of Anderson Localization and Quantum Scarring in Two Dimensions
Fartash Chalangari, Anant Vijay Varma, Joonas Keski-Rahkonen +1
We investigate finite two-dimensional disordered systems with periodic confinement. At low energies, eigenstates exhibit strong Anderson localization, while at higher energies a su…
