Electron pairing: from metastable electron pair to bipolaron [PDF]
, 2018 Starting from the shell structure in atoms and the significant correlation within electron pairs, we distinguish the exchange-correlation effects between two electrons of opposite spins occupying the same orbital from the average correlation among many electrons in a crystal.

First-principles calculations of hot-electron lifetimes in metals [PDF]
Phys. Rev. B 61, 13484 (2000), 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 within the GW approximation of many-body theory.

Insights into the Electron-Electron Interaction from Quantum Monte Carlo Calculations [PDF]
arXiv, 2021 The effective electron-electron interaction in the electron gas depends on both the density and spin local field factors. Variational Diagrammatic Quantum Monte Carlo calculations of the spin local field factor are reported and used to quantitatively present the full spin-dependent, electron-electron interaction.

D'yakonov-Perel' spin relaxation for degenerate electrons in the electron-hole liquid [PDF]
Phys. Rev. B 83, 155205 (2011), 2010 We present an analytical study of the D'yakonov-Perel' spin relaxation time for degenerate electrons in a photo-excited electron-hole liquid in intrinsic semiconductors exhibiting a spin-split band structure. The D'yakonov-Perel' spin relaxation of electrons in these materials is controlled by electron-hole scattering, with small corrections from ...

First-principles calculations of heat capacities of ultrafast laser-excited electrons in metals [PDF]
Applied Surface Science, Elsevier, 2015, 336, pp.79-84, 2015 Ultrafast laser excitation can induce fast increases of the electronic subsystem temperature. The subsequent electronic evolutions in terms of band structure and energy distribution can determine the change of several thermodynamic properties, including one essential for energy deposition; the electronic heat capacity.

Electron-Electron Bremsstrahlung Emission and the Inference of Electron Flux Spectra in Solar Flares [PDF]
, 2007 Although both electron-ion and electron-electron bremsstrahlung contribute to the hard X-ray emission from solar flares, the latter is normally ignored. Such an omission is not justified at electron (and photon) energies above $\sim 300$ keV, and inclusion of the additional electron-electron bremsstrahlung in general makes the electron spectrum ...

Born-Oppenheimer Dynamics, Electronic Friction, and the Inclusion of Electron-Electron Interactions [PDF]
Phys. Rev. Lett. 119, 046001 (2017), 2017 We present a universal expression for the electronic friction as felt by a set of classical nuclear degrees of freedom (DoF's) coupled to a manifold of quantum electronic DoF's; no assumptions are made regarding the nature of the electronic Hamiltonian and electron-electron repulsions are allowed.

Emergence and spectral-weight transfer of electronic states in the Hubbard ladder [PDF]
Phys. Rev. B 100, 235143 (2019), 2019 The number of electronic bands is usually considered invariant regardless of the electron density in a band picture. However, in interacting systems, the spectral-weight distribution generally changes depending on the electron density, and electronic states can even emerge or disappear as the electron density changes.
