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…
