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…
Variational Scarring in Open Two-Dimensional Quantum Dots
Fartash Chalangari, Joonas Keski-Rahkonen, Simo Selinummi +1
Quantum scars have recently been directly visualized in graphene quantum dots (Nature 635, 841 (2024)), revealing their resilience and influence on electron dynamics in mesoscopic…
Formation, prevalence, and stability of bouncing-ball quantum scars
Simo Selinummi, Joonas Keski-Rahkonen, Fartash Chalangari +1
Quantum scars correspond to enhanced probability densities along unstable classical periodic orbits. In recent years, research on quantum scars has extended to various systems incl…
Ground-state magnetization of the Ising spin glass: A recursive numerical method and Chen-Ma scaling
Reza Sepehrinia, Fartash Chalangari
The ground-state properties of quasi-one-dimensional (Q1D) Ising spin glass are investigated using an exact numerical approach and analytical arguments. A set of coupled recursive…
