Confinement contains condensates

open access: yes, 2012
Dynamical chiral symmetry breaking and its connection with the generation of hadron masses has historically been viewed as a vacuum phenomenon. We argue that confinement makes such a position untenable.

SOLPS-ITER modeling of neon-seeded EAST plasmas under connected double-null configurations and its impact on tungsten impurity behaviors

open access: yesNuclear Fusion
The SOLPS-ITER edge modeling package was employed to numerically investigate neon (Ne)-seeded EAST plasmas under connected-double-null configurations, focusing on Ne impurity transport and its impacts on tungsten (W) impurity behaviors.

Determination of the strong coupling alpha_s from the QCD static energy [PDF]

open access: yes, 2012
We obtain a determination of the strong coupling alpha_s in quantum chromodynamics, by comparing perturbative calculations for the short-distance part of the static energy with lattice computations.

Numerical study of linear and circular model DNA chains confined in a slit: metric and topological properties

open access: yes, 2012
Advanced Monte Carlo simulations are used to study the effect of nano-slit confinement on metric and topological properties of model DNA chains. We consider both linear and circularised chains with contour lengths in the 1.2--4.8 $\mu$m range and slits ...

First application of the island divertor configuration in the J-TEXT tokamak

open access: yesNuclear Fusion
For the first time, an island divertor configuration was successfully implemented in the J-TEXT tokamak to improve heat exhaust and impurity control. The magnetic island is generated by applying external resonant magnetic perturbation fields, and the ...

Hypocoercivity without confinement [PDF]

open access: yes, 2019
In this paper, hypocoercivity methods are applied to linear kinetic equations with mass conservation and without confinement, in order to prove that the solutions have an algebraic decay rate in the long-time range, which the same as the rate of the heat

Overview of the recent experimental research on the J-TEXT tokamak

open access: yesNuclear Fusion
The J-TEXT capability is enhanced compared to two years ago with several upgrades of its diagnostics and the increase of electron cyclotron resonance heating (ECRH) power to 1 MW.

On how finite β and three-dimensional magnetic perturbations affect the instability of toroidal ion temperature gradient mode

open access: yesNuclear Fusion
The effects of finite $\beta $ (the ratio of plasma kinetic pressure to magnetic pressure) and three-dimensional (3D) magnetic perturbations (MPs) on the instability of toroidal ion temperature gradient (ITG) mode are studied in this work. The expression

Kinetic theory of helium ash source from distribution function of He ions and its effects on helium ash density profile

open access: yesNuclear Fusion
In this work, the source of helium (He) ash is explicitly defined in terms of the full energy distribution function of He ions in deuterium–tritium burning plasmas, and the He ash density profile is subsequently predicted by considering both source and ...

Optimization of Organic Content Removal from Aqueous Solutions by Fenton-Ozonation

open access: yesApplied Sciences
This paper presents a study on the optimization of 2,4-Dichlorophenoxyacetic (2,4-D) acid removal from synthetic wastewater by batch Fenton-Ozonation. The aim of this study is to evaluate the potential of the catalytic system Fe-L27 coupled to ozonation ...
