Ab initio calculation of low-energy collective charge-density excitations in MgB2
(American Physical Society, 2009-08)
We present ab initio time-dependent density-functional theory calculation results for low-energy collective electron excitations in MgB2. The existence of a long-lived collective excitation corresponding to coherent charge ...
Energy loss of charged particles moving parallel to a magnesium surface
(American Physical Society, 2008-10)
We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical ...
First-principles calculations of hot-electron lifetimes in metals
(American Physical Society, 2000)
First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ...
