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.

Free-electron properties of metals under ultrafast laser-induced electron-phonon nonequilibrium: A first-principles study [PDF]
Physical Review B (Condensed Matter) 89 (2014) 115117, 2014 The electronic behavior of various solid metals (Al, Ni, Cu, Au, Ti, and W) under ultrashort laser irradiation is investigated by means of density functional theory. Successive stages of extreme nonequilibrium on picosecond time scale impact the excited material properties in terms of optical coupling and transport characteristics.

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.

Dynamic correlations in symmetric electron-electron and electron-hole bilayers
, 2002 The ground-state behavior of the symmetric electron-electron and electron-hole bilayers is studied by including dynamic correlation effects within the quantum version of Singwi, Tosi, Land, and Sjolander (qSTLS) 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 ...

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...
