Collective modes in a quasi-one-dimensional, two-component electron liquid
(Pergamon Press, 1994)Under favorable conditions, a new collective mode besides the usual plasmons may exist in degenerate electron-hole liquids. We calculate the dispersion and damping of this new mode (called the acoustic plasmon mode) in a ... -
Lattice dynamics and elastic properties of lanthanum monopnictides
(2008)In this study, first principles calculation results of the second order elastic constants and lattice dynamics of two lanthanum monopnictides, LaN and LaBi, which crystallize in rock-salt structure (B1 phase), are presented. ... -
Vibrational and thermodynamic properties of α-, β-, γ-, and 6, 6, 12-graphyne structures
(Institute of Physics Publishing, 2014)Electronic, vibrational, and thermodynamic properties of different graphyne structures, namely α-, β-, γ-, and -graphyne, are investigated through first principles-based quasi-harmonic approximation by using phonon dispersions ...
