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

Modeling of Polarization-Specific Phonon Transmission Through Interfaces [PDF]
, 2011 In this work, the atomistic Green\u27s function method is extended to compute transmission functions for each phonon polarization. The eigenvectors and eigenvalues of the overall density of states matrices are manipulated to yield a density of states ...

Bosonic spectral function and the electron-phonon interaction in HTSC cuprates [PDF]
, 2010 In this paper we discuss experimental evidence related to the structure and origin of the bosonic spectral function alpha 2F (omega) in high-temperature superconducting (HTSC) cuprates at and near optimal doping.

Temperature Dependence of Phonons in Elemental Cubic Metals Studied by Inelastic Scattering of Neutrons and X-Rays [PDF]
, 2009 The vibrations of atoms in a crystal (phonons) make up the majority of its entropy (or heat capacity), and these vibrations are typically modeled by simple harmonic oscillators.

Optical-phonon resonances with saddle-point excitons in twisted-bilayer graphene [PDF]
, 2014 Twisted-bilayer graphene (tBLG) exhibits van Hove singularities in the density of states that can be tuned by changing the twisting angle θ. A θ-defined tBLG has been produced and characterized with optical reflectivity and resonance Raman scattering ...
