Anharmonicity-induced phonon broadening in aluminum at high temperatures [PDF]

open access: yes, 2010
Thermal phonon broadening in aluminum was studied by theoretical and experimental methods. Using second-order perturbation theory, phonon linewidths from the third-order anharmonicity were calculated from first-principles density-functional theory (DFT)

Multiple Weyl and double-Weyl points in the phonon dispersion of P4332 BaSi2

open access: yesFrontiers in Physics, 2023
Weyl semimetals, classified as solid-state crystals and whose Fermi energy is accurately situated at Weyl points (WPs), have received much attention in condensed matter physics over the past 10 years.

Phononic thermal conductivity in silicene: the role of vacancy defects and boundary scattering [PDF]

open access: yes, 2017
We calculate the thermal conductivity of free-standing silicene using the phonon Boltzmann transport equation within the relaxation time approximation.

Quantum “contact” friction: The contribution of kinetic friction coefficient from thermal fluctuations

open access: yesFriction, 2023
A thermal model of kinetic friction is assigned to a classical loaded particle moving on a fluctuating smooth surface. A sinusoidal wave resembles surface fluctuations with a relaxation time. The Hamiltonian is approximated to the mean energy of the wave

Phonon Josephson Junction with Nanomechanical Resonators [PDF]

open access: yes, 2016
We study coherent phonon oscillations and tunneling between two coupled nonlinear nanomechanical resonators. We show that the coupling between two nanomechanical resonators creates an effective phonon Josephson junction which exhibits two different ...

Phonon-phonon interactions and phonon damping in carbon nanotubes [PDF]

open access: yesPhysical Review B, 2009
We formulate and study the effective low-energy quantum theory of interacting long-wavelength acoustic phonons in carbon nanotubes within the framework of continuum elasticity theory. A general and analytical derivation of all three- and four-phonon processes is provided, and the relevant coupling constants are determined in terms of few elastic ...
