To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

In the past few decades, numerous heat conduction models extending beyond Fourier's
have been developed to account for large gradients, fast phenomena, wave propagation …

We introduce a novel approach to model heat transport in solids, based on the Green-Kubo
theory of linear response. It naturally bridges the Boltzmann kinetic approach in crystals and …

ABSTRACT Coupling of the Peierls-Boltzmann equation with density functional theory
paved the way for predictive thermal materials discovery and a variety of new physical …

Phonon hydrodynamics is an exotic phonon transport phenomenon that challenges the
conventional understanding of diffusive phonon scattering in crystalline solids. It features a …

Thermal conductivity is a crucial material property for a diverse range of energy
technologies, ranging from thermal management of high power electronics to thermal …

Lattice thermal conductivities of two SiO 2 polymorphs, ie, α quartz (low) and α cristobalite
(low), were studied using first-principles anharmonic phonon calculation and linearized …

Polymeric materials are ubiquitous in our everyday life, where they find a broad range of
uses—spanning across common household items to advanced materials for modern …

The performance of thermoelectric materials is determined by their electrical and thermal
transport properties that are very sensitive to small modifications of composition and …

We study the mutual coupling of spin fluctuations and lattice vibrations in paramagnetic CrN
by combining atomistic spin dynamics and ab initio molecular dynamics. The two degrees of …
