Spillway preheating

Journal of High Energy Physics, 2021
In traditional models only an order one fraction of energy is transferred from the inflaton to radiation through nonperturbative resonance production in preheating immediately after inflation, due to backreaction effects. We propose a particle production

Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy

Advanced Engineering Materials, EarlyView.
The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Wave–particle interactions in tokamaks

Nuclear Fusion
Transport consequences of the wave–particle interactions in the quasilinear plateau (QP) regime are presented. Eulerian approach is adopted to solve the drift kinetic equation that includes the physics of the nonlinear trapping (NT) and QP regimes.

Generalised Known Kinematics (GKK): an approach for kinematic observables in pair production events with decays involving invisible particles

Journal of High Energy Physics, 2023
Missing kinematic information of known invisible particles, such as neutrinos, limit several high-energy physics analysis. The undetected particle carries away momentum and energy information, preventing the total reconstruction of such an event.

Investigations on particle dynamics in a high intensity heavy ion linac for inertial fusion [PDF]

, 2005
Die Physik intensiver Ionenstrahlen wird zur Zeit für verschiedene neue Hochstrom- und Hochenergie-Beschleunigeranlagen untersucht. Ein kritischer Punkt ist dabei die Minimierung der Strahlverluste, um die Aktivierung der Beschleunigerstruktur zu ...

A new approach to numerical characterisation of wear particle surfaces in three-dimensions for wear study [PDF]

, 2012
In the wear and tear process of synovial joints, wear particles generated and released from articular cartilage within the joints have surface topography and mechanical property which can be used to reveal wear conditions. Three-dimensional (3D) particle

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Adversarially-trained autoencoders for robust unsupervised new physics searches

Journal of High Energy Physics, 2019
Machine learning techniques in particle physics are most powerful when they are trained directly on data, to avoid sensitivity to theoretical uncertainties or an underlying bias on the expected signal.

Heavy Ion Physics with CMS Detector [PDF]

, 2002
The CMS detector is well suited to study heavy ion physics. Hermetic calorimetry, a precise inner tracking and a background free muon system make possible to study a wide range of phenomena, including quark-gluon plasma (QGP) formation.
