On the origin of energy gaps in quasicrystalline potentials
Emmanuel Gottlob, David Gröters, Ulrich Schneider
Quasicrystals, structures that are ordered yet aperiodic, defy conventional band theory, confining most studies to finite-size real-space numerics. We overcome this limitation with…

Superfluid-Mott transition in a frustrated triangular optical lattice
Mehedi Hasan, Luca Donini, Sompob Shanokprasith +7
Geometric frustration can significantly increase the complexity and richness of many-body physics and, for instance, suppress antiferromagnetic order in quantum magnets. Here, we e…

Quasiperiodicity protects quantized transport in disordered systems without gaps
Emmanuel Gottlob, Dan S. Borgnia, Robert-Jan Slager +1
The robustness of topological properties, such as quantized currents, generally depends on the existence of gaps surrounding the relevant energy levels or on symmetry-forbidden tra…
