Interplay of spin-orbit coupling and Coulomb interaction in ZnO-based electron system [PDF]

open access: yes, 2020
Spin-orbit coupling (SOC) is pivotal for various fundamental spin-dependent phenomena in solids and their technological applications. In semiconductors, these phenomena have been so far studied in relatively weak electron-electron interaction regimes, where the single electron picture holds.

Electron pairing: from metastable electron pair to bipolaron [PDF]

open access: yes, 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]

open access: yesPhysical 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]

open access: yesPhys. 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.

The power of microRNA regulation—insights into immunity and metabolism

open access: yesFEBS 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 ...

Quantum Theory of Scattering of Nonclassical Fields by Free Electrons

open access: yesMathematics, 2023
At present, there is no non-perturbative theory of scattering of nonclassical electromagnetic waves by free electrons that describes the scattering process completely with the help of quantum physics.

Insights into the Electron-Electron Interaction from Quantum Monte Carlo Calculations [PDF]

open access: yesarXiv, 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]

open access: yesPhys. 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 ...

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...
