Sophisticated momenta mapping with DIANA

, 2005
Details of recent developments of the Feynman diagram analyzer DIANA (DIagram ANAlyser) are presented. Apart from some discussion about QGRAF and new plotting features, we concentrate on a new sophisticated mechanism of momenta mapping.Comment: 4 pages ...

Constructing Serrated Boride Composite Layer for Enhancing Wear Resistance of Ti6Al4V Alloy

Rare Metals, EarlyView.
ABSTRACT Appropriate configuration combined with strong interface bonding is the essential requirement for developing high wear‐resistant coatings. Herein, based on the powder‐pack boriding process, the properties of Ti6Al4V alloy are effectively improved by constructing a serrate tribological boride composite layer.

The Born regime of gravitational amplitudes

Journal of High Energy Physics
We study the 2 → 2 scattering in the regime where the wavelength of the scattered objects is comparable to their distance but is much larger than any Compton wavelength in the quantum field theory.

Orbitally Driven Anomalous Thermal Transport Under High Pressure in Gallium Nitride

Rare Metals, EarlyView.
ABSTRACT Extreme conditions such as high pressure offer opportunities for innovative materials design and applications. For over a century, studies on thermal transport in crystals under high hydrostatic pressure have shown that lattice thermal conductivity generally exhibits a monotonic increase with pressure.

The propagator seagull: general evaluation of a two loop diagram

Journal of High Energy Physics, 2019
We study a two loop diagram of propagator type with general parameters through the Symmetries of Feynman Integrals (SFI) method. We present the SFI group and equation system, the group invariant in parameter space and a general representation as a line ...

Comment on "Summing One-Loop Graphs at Multi-Particle Threshold"

, 1992
The propagator of a virtual $\phi$-field with emission of $n$ on-mass-shell particles all being exactly at rest is calculated at the tree-level in $\lambda \phi^4$ theory by directly solving recursion equations for the sum of Feynman graphs.

A Micro‐Nano Flower‐Like Na3V2(PO4)3@C Constructed by Polar‐Driven H‐Bond Engineering Toward High‐Rate Sodium Storage

Rare Metals, EarlyView.
ABSTRACT The polyanionic compound Na3V2(PO4)3 (NVP) has emerged as a competitive cathode material for sodium‐ion batteries (SIBs), owing to its high‐voltage redox activity (3.4 V vs. the Na+/Na reference couple) and NASICON‐type framework that enables superior ionic conductivity.

A High Capacity‐Long Cycling Concurrent Strategy of Ti3C2/MgH2 for Lithium Storage

Rare Metals, EarlyView.
ABSTRACT The excellent electrical conductivity and superior cycling stability render Ti3C2 MXene a promising Li ion battery anode. Nevertheless, the practical implementation of Ti3C2 MXene in commercial applications faces significant challenges, predominantly due to the low specific capacity.

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

Small, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization
