It is by now well established that Dirac fermions coupled to non-Abelian gauge theories can
undergo an Anderson-type localization transition. This transition affects eigenmodes in the …

We study disorder effects in a two-dimensional system with chiral symmetry and find that
disorder can induce a quadrupole topological insulating phase (a higher-order topological …

We study the electronic properties of DNA by way of a tight-binding model applied to four
particular DNA sequences. The charge transfer properties are presented in terms of …

We propose efficient preconditioning algorithms for an eigenvalue problem arising in
quantum physics, namely, the computation of a few interior eigenvalues and their associated …

Amphiphilic block copolymer membranes, classified as vesicles, are nano-aggregates
receiving a lot of scientific interest due to their wide range of potential applications extending …

Partially reduced graphene oxide (prGO) obtained by hydrothermal reduction was studied
by electron paramagnetic resonance (EPR) spectroscopy in the temperature range 4.2–300 …

We study the localization properties of the eigenmodes of the staggered Dirac operator in
finite-temperature Z 2 pure gauge theory on the lattice in 2+ 1 dimensions. We find that the …

We study the localization properties and the Anderson transition in the three-dimensional
Lieb lattice L 3 (1) and its extensions L 3 (n) in the presence of disorder. We compute the …

Results of large-scale numerical simulations are reported on the Anderson localization in a
two-dimensional square lattice tight-binding model with random flux. Localization lengths …

We study energy spectra, eigenstates, and quantum diffusion for one-and two-dimensional
quasiperiodic tight-binding models. As for our one-dimensional model system we choose …
