Approximating spectral densities of large matrices

L Lin, Y Saad, C Yang - SIAM review, 2016 - SIAM
In physics, it is sometimes desirable to compute the so-called density of states (DOS), also
known as the spectral density, of a real symmetric matrix A. The spectral density can be …

Conduction tuning of graphene based on defect-induced localization

S Nakaharai, T Iijima, S Ogawa, S Suzuki, SL Li… - ACS …, 2013 - ACS Publications
The conduction properties of graphene were tuned by tailoring the lattice by using an
accelerated helium ion beam to embed low-density defects in the lattice. The density of the …

Understanding the electronic pi-system of 2D covalent organic frameworks with Wannier functions

K Merkel, J Greiner, F Ortmann - Scientific Reports, 2023 - nature.com
We investigate a family of hexagonal 2D covalent organic frameworks (COFs) with phenyl

Anderson localization in two-dimensional graphene with short-range disorder: One-parameter scaling and finite-size effects

Z Fan, A Uppstu, A Harju - Physical Review B, 2014 - APS
We study Anderson localization in graphene with short-range disorder using the real-space
Kubo-Greenwood method implemented on graphics processing units. Two models of short …

Resilience of Majorana fermions in the face of disorder

A Habibi, SA Jafari, S Rouhani - Physical Review B, 2018 - APS
We elucidate the reduction of the winding number caused by the on-site disorder in a next-
nearest-neighbor XY model. When disorder becomes strong enough, Majorana edge modes …
