Correlation‐Driven d‐Band Modifications Promote Chemical Bonding at 3d‐Ferromagnetic Surfaces

Small, EarlyView.
Electron correlation at the oxygen‐passivated Fe(100) surface renormalizes and narrows the Fe d‐bands, enhancing their energetic overlap with the frontier orbitals of adsorbed pentacene. This strengthens hybridization and converts a weakly bound interface into a chemisorbed hybrid system, illustrating how correlation‐tuned d‐bands can be used to ...

Tunable Colloidal Synthesis Enabling μ‐ARPES on Individual Bismuth Nanocrystals

Small, EarlyView.
We report a highly controlled colloidal synthesis of Bi nanosheets with tunable lateral sizes (0.6–4.1 µm), hexagonal shape, and a layered single‐crystalline structure along the {00l} planes. The nanosheets feature high phase purity and excellent ambient stability. Remarkably, O2 promotes larger lateral growth with ultra‐smooth surfaces. This scalable,

Dimuons from neutrino-nucleus collisions in the semi-inclusive DIS approach

Journal of High Energy Physics
We present a next-to-leading order perturbative QCD calculation of dimuon production in neutrino-nucleus collisions. This process is typically calculated by assuming it to be proportional to inclusive charm production, which requires an effective ...

Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

Small, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Towards unifying perturbative and Holographic Light-Front QCD via holomorphic coupling

Journal of High Energy Physics
We construct a QCD coupling A $$ \mathcal{A} $$ (Q 2) in the Effective Charge (ECH) scheme of the canonical part d(Q 2) of the (inelastic) polarised Bjorken Sum Rule (BSR) Γ ¯ 1 p − n $$ {\overline{\Gamma}}_1^{\textrm{p}-\textrm{n}} $$ (Q 2).

Novel Aspects of Hard Diffraction in QCD

, 2005
Initial- and final-state interactions from gluon-exchange, normally neglected in the parton model have a profound effect in QCD hard-scattering reactions, leading to leading-twist single-spin asymmetries, diffractive deep inelastic scattering ...

Live Imaging of Silver Nanostructures Electrochemically Dissolving at Open‐Circuit Potential

Small, EarlyView.
Stability of electrocatalysts as used in energy conversion systems is pivotal for sustainable technologies, yet degradation dynamics at the nanoscale remain elusive. Harnessing beam‐effect corrected electrochemical liquid phase electron microscopy combined with correlative bulk‐scale electrochemical testing reveals silver corrosion on platinum under ...

An FONLL prescription with coexisting flavor number PDFs

Journal of High Energy Physics
We present a new prescription to account for heavy quark mass effects in the determination of parton distribution functions (PDFs) based on the FONLL scheme.

Single‐Particle Characterization Reveals Heterogeneous Extracellular Vesicle Fusion with Liposomes

Small Methods, EarlyView.
This study used five orthogonal single‐particle techniques to compare how common mechanical methods fuse extracellular vesicles with liposomes. By quantifying fused‐particle yield, purity, and vesicle integrity, we found that freeze‐thaw and sonication generated the highest fusion but that all methods introduced membrane perturbation or damage.

Complete N f 2 $$ {N}_f^2 $$ contributions to four-loop pure-singlet splitting functions

Journal of High Energy Physics
The scale evolution of parton distributions is determined by universal splitting functions. As a milestone towards the computation of these functions to four-loop order in QCD, we compute all contributions to the pure-singlet quark-quark splitting ...
