Enhanced compressibility due to repulsive interaction in the Harper model
Yaacov E. Kraus, Oded Zilberberg, Richard Berkovits
We study the interplay between repulsive interaction and an almost staggered on-site potential in one-dimension. Specifically, we address the Harper model for spinless fermions wit…
Comment on "Topological equivalence of crystal and quasicrystal band structures"
Yaacov E. Kraus, Zohar Ringel, Oded Zilberberg
Madsen et al. [arXiv:1307.2577] claim that one-dimensional insulating crystals and one-dimensional insulating quasicrystals are topologically equivalent and, thus, trivial. In this…
Four-Dimensional Quantum Hall Effect in a Two-Dimensional Quasicrystal
Yaacov E. Kraus, Zohar Ringel, Oded Zilberberg
One-dimensional (1D) quasicrystals exhibit physical phenomena associated with the 2D integer quantum Hall effect. Here, we transcend dimensions and show that a previously inaccessi…
