Wigner formulation of thermal transport in solids

M Simoncelli, N Marzari, F Mauri - Physical Review X, 2022 - APS
Two different heat-transport mechanisms are discussed in solids. In crystals, heat carriers
propagate and scatter particlelike as described by Peierls's formulation of the Boltzmann …

Significant anharmonicity of thermal transport in amorphous silica at high temperature

L Yang, BY Cao - physica status solidi (RRL)–Rapid Research …, 2022 - Wiley Online Library
The anharmonicity of thermal transport in amorphous solids is underappreciated and
inadequately understood, although considerable attention is paid to that of crystals. Herein …

Viscous heat backflow and temperature resonances in extreme thermal conductors

J Dragašević, M Simoncelli - arXiv preprint arXiv:2303.12777, 2023 - arxiv.org
We demonstrate that non-diffusive, fluid-like heat transport, such as heat backflowing from
cooler to warmer regions, can be induced, controlled, and amplified in extreme thermal …

Advances in lattice thermal transport in crystals and glasses

A Fiorentino - 2024 - iris.sissa.it
Thermal conductivity is a fundamental property for describing the non-equilibrium
phenomenon of thermal transport. In solid insulators, whether disordered or crystalline, heat …

Heat transport in binary semiconductor polytypes and devices based on 2D materials: an ab initio study

M Raya Moreno - 2022 - ddd.uab.cat
In this thesis we calculate, using first principles and solving the Phonon Boltzmann Transport
Equation, the lattice thermal conductivity for binary semiconductor polytypes. First, we …
