Multivalued Memory via Freezing of Super‐Hard Magnetic Domains in a Quasi 2D‐Magnet

Small Methods, Volume 7, Issue 11, November 16, 2023., 2023
The 2D‐Ising ferromagnet BaFe2(PO4)2, is affected below 15 K by the freezing of its magnetic domains due to giant magneto‐crystalline anisotropy and intrinsic pinning of the narrow domain walls. It results in a transition from a soft to a super‐hard magnet with record‐coercive force greater than 14 T, and allows for the writing, robust locking and ...

Advancing Our Understanding of Martian Proton Aurora Through a Coordinated Multi‐Model Comparison Campaign

Journal of Geophysical Research: Space Physics, Volume 128, Issue 10, October 2023., 2023
Abstract Proton aurora are the most commonly observed yet least studied type of aurora at Mars. In order to better understand the physics and driving processes of Martian proton aurora, we undertake a multi‐model comparison campaign. We compare results from four different proton/hydrogen precipitation models with unique abilities to represent Martian ...

Rise of the DIS structure function F L at small x caused by double-logarithmic corrections

Journal of High Energy Physics, 2021
We present calculation of F L in the double-logarithmic approximation (DLA) and demonstrate that the synergic effect of the factor 1/x from the α s 2 $$ {\alpha}_s^2 $$ -order and the steep x-dependence of the totally resummed double logarithmic ...

Precise QCD Predictions for the Production of Dijet Final States in Deep Inelastic Scattering. [PDF]

Physical Review Letters, 2016
The production of two-jet final states in deep inelastic scattering is an important QCD precision observable. We compute it for the first time to next-to-next-to-leading order (NNLO) in perturbative QCD.

A Unifying Perspective of Common Motifs That Occur across Disparate Classes of Materials Harboring Displacive Phase Transitions

Advanced Energy Materials, Volume 13, Issue 30, August 11, 2023., 2023
This perspective reveals overarching and recurring motifs of displacive (martensitic) phase transitions such as twinned microstructure, transport anomalies, and phonon softening. However, these phase transitions are often studied in different communities; bringing them together is expected to provide opportunities for future research. Important classes

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond

Journal of High Energy Physics, 2020
We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...

Kinematic distributions of the η c leptoproduction in association with light hadrons

Journal of High Energy Physics, 2021
The η c meson leptoproduction is calculated within the nonrelativistic QCD framework for the first time. It is found that the colour-singlet channel, although suppressed by a factor of α s relative to the colour-octet ones, provides important ...

Thermoplasmonic Manipulation for the Study of Single Polymers and Protein Aggregates

Macromolecular Chemistry and Physics, Volume 224, Issue 14, July 2023., 2023
Thermoplasmonics, that is, the generation of heat with plasmonic nanostructures has recently found new applications in the manipulation of single macromolecules and protein aggregates. Recent developments are reviewed with a specific focus on thermophoretic trapping of single nano‐objects and highlight the connection to temperature induced hydrodynamic

A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization

Journal of High Energy Physics, 2021
We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent

Glass transition, topology, and elastic models of Se‐based glasses

Journal of the American Ceramic Society, Volume 106, Issue 6, Page 3277-3302, June 2023., 2023
Abstract Features intrinsic to disorder and network aspects are ubiquitous in structural glasses. Among this important class of materials, chalcogenide glasses are special—they are built of short‐range covalent forces, making them simpler than silicate glasses that possess mixed ionic and covalent forces.
