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…
Nonperturbative computation of thermal conductivity based on Path Integral Monte Carlo methods
Vladislav Efremkin, Stefano Mossa, Jean-Louis Barrat +1
The calculation of thermal conductivity in insulating solids at temperatures below the Debye temperature is problematic, due to the breakdown of classical and semi-classical approa…
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…
Time correlation functions for quantum systems: validating Bayesian approaches for harmonic oscillators and beyond
Vladislav Efremkin, Jean-Louis Barrat, Stefano Mossa +1
The quantum harmonic oscillator is the fundamental building block to compute thermal properties of virtually any dielectric crystal at low temperatures in terms of phonons, extende…
