The generalized self-consistent field method is used to describe intraband relaxation processes in a general multiband electronic system with presumably weak residual electron-electron interactions. The resulting memory-function conductivity formula is shown to have the same structure as the result of a more accurate approach based on the quantum kinetic equation. The results are applied to heavily doped and lightly doped graphene. It is shown that the scattering of conduction electron by…

Memory-function conductivity formula and transport coefficients in underdoped cuprates

Abstract The two-band memory-function conductivity formula is derived from the quantum kinetic equation in the pseudogap state of underdoped cuprates. The conduction electrons are described by using

Phonon-assisted damping of plasmons in three- and two-dimensional metals

We investigate the effects of crystal lattice vibrations on the dispersion of plasmons. The loss function of the homogeneous electron gas (HEG) in two and three dimensions is evaluated numerically in

Dopant-Induced Plasmon Decay in Graphene.

New dopant-activated damping channels are found in single-layer and bilayer graphene doped with various alkali and alkaline earth metals: loss due to out-of-plane graphene and in-plane dopant vibrations, and electron transitions between graphene and dopant states.

Electron-Mediated Phonon-Phonon Coupling Drives the Vibrational Relaxation of CO on Cu(100).

A consistent theory for the electron-mediated vibrational intermode coupling is brought forth that clarifies the microscopic mechanism behind the vibrational relaxation of adsorbates on metal surfaces and is able to explain the temperature dependence of the internal stretch phonon linewidth.

A comparative study of finite frequency scattering rate from Allen, Mitrović–Fiorucci, Shulga–Dolgov–Maksimov, Sharapov–Carbotte and memory function formalisms

We report a comparative study of scattering rates which are calculated using different formalisms such as [P. B. Allen, Phys. Rev. B 3, 305 (1971); S. V. Shulga, D. V. Dolgov and E. G. Maksimov,



I and i

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
