From Bellissard's gap labeling to atomistic quasiperiodic bilayers
Thomas D. Kühne, Vladislav Efremkin, Emil Prodan
Bellissard's framework uses covariant observables to describe aperiodic solids. We examine how butterfly-like spectra in twisted bilayers can be related to bulk gap labels and topo…

Quantifying Gibbs measures of disordered crystals up to the solid-liquid phase transition
Vladislav Efremkin, Julian Heske, Thomas D. Kühne +1
Quantifying the configuration space and the Gibbs measure of thermally disordered condensed matter systems has been a long standing problem. The challenge is to avoid the Gibbs par…
