No Confinement without Coulomb Confinement [PDF]
Physical Review Letters, 2003 We compare the physical potential $V_D(R)$ of an external quark-antiquark pair in the representation $D$ of SU(N), to the color-Coulomb potential $V_{\rm coul}(R)$ which is the instantaneous part of the 44-component of the gluon propagator in Coulomb gauge, $D_{44}(\vx,t) = V_{\rm coul}(|\vx|) (t)$ + (non-instantaneous).

CONSTRUCTING CONFINEMENT [PDF]
Fundamental Interactions, 2003 The interaction between static quarks is derived by applying many-body techniques to QCD in Coulomb gauge. The result is shown to be exact in the IR and UV limits, and agrees remarkably well with lattice computations.

Topology and confinement [PDF]
Nuclear Physics B - Proceedings Supplements, 2009 These lectures contain an introduction to instantons, calorons and dyons of the Yang--Mills gauge theory. Since we are interested in the mechanism of confinement and of the deconfinement phase transition at some critical temperature, the Yang--Mills theory is formulated and studied at nonzero temperatures.

Confinement as crossover [PDF]
, 2000 The order parameter of confinement together with the haaron model of the QCD vacuum is reviewed and it is pointed out that confining forces are generated by the non-renormalizable, invariant Haar-measure vertices of the path integral. A hybrid model is proposed for the description of the crossover leading to the confining vacuum. This scenario suggests

Progression of Myopia in School-Aged Children After COVID-19 Home Confinement
JAMA ophthalmology, 2021 Key Points Question Is home confinement due to coronavirus disease 2019 associated with the burden of myopia? Findings In this cross-sectional study that included 194 904 photoscreening tests conducted in 123 535 children, a substantial myopic shift (−0 ...

Influence of COVID-19 confinement in students performance in higher education [PDF]
arXiv.org, 2020 This study explores the effects of COVID-19 confinement in the students’ performance in higher education. Using a field experiment of 458 students from three different subjects in Universidad Autónoma de Madrid (Spain), we study the differences in ...

Confinement on the brane [PDF]
Nuclear Physics B, 2000 A non-perturbative confinement mechanism has been proposed to explain the fate of the unbroken gauge group on the world-volume of annihilating D-brane-anti-D-brane pairs. In this paper, we examine this phenomenon closely from several different perspectives.
