Confinement and Spin [PDF]

open access: yesInternational Journal of Modern Physics A, 1997
The experimental and theoretical evidence relating spin dependence and long range confinement is reviewed. One of the simplest confinement ideas, the dynamic electric flux tube picture of Buchmüller, can be exploited to yield a complete effective Hamiltonian.

Theory of color confinement: state of the art

open access: yes, 2001
The existing evidence for dual superconductivity as mechanism of color confinement is reviewed. We also discuss what is known on the dual excitations, which produce confinement by condensation, and what are the open ...

Heterostructure‐Specific Toughening Mechanisms in Metallic Laminates

open access: yesAdvanced Engineering Materials, EarlyView.
This study highlights how various aspects of the heterostructural design of metallic laminates can be specifically tailored to achieve improved fracture resistance for damage‐tolerant designs of cyclically stressed components. Based on results from in situ fatigue crack growth tests, a comprehensive overview of the formation and development of ...

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

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 ...

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

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 ...

Diffusion in Confined Geometries

open access: yesChemPhysChem, 2009
AbstractDiffusive transport of particles or, more generally, small objects, is a ubiquitous feature of physical and chemical reaction systems. In configurations containing confining walls or constrictions, transport is controlled both by the fluctuation statistics of the jittering objects and the phase space available to their dynamics.

Confinement and electron correlation effects in photoionization of atoms in endohedral anions: Ne@C60^{z-}

open access: yes, 2009
Trends in resonances, termed confinement resonances, in photoionization of atoms A in endohedral fullerene anions A@C60^{z-} are theoretically studied and exemplified by the photoionization of Ne in Ne@C{60}^{z-}.
