Iris bismarckiana in Israel and Jordan—New findings and taxonomic remarks
2001
Iris bismarckiana (Iris section Oncocyclus) was found for the first time in the west Gilead in Jordan. This discovery was utilized to shed some light on the taxonomic relationships among the light-colored irises in the Levant. Morphometric quantitative analysis of the Jordanian population compared to I. bismarckiana allies in Israel (I. bismarckiana in the Galilee and I. hermona in the Golan) suggests that the Jordanian population is I. bismarckiana, despite the large distance from the main distribution area. Cluster analysis, based on the morphology, revealed that some of the populations of I. bismarckiana have closer affinities to I. hermona than to each other. Populations of I. hermona a…
Low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain
2014
We derive the low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain by summing up the asymptotically dominant terms of their expansion into form factors of the quantum transfer matrix. Our asymptotic formulae are numerically efficient and match well with known results for vanishing magnetic field and for short distances and magnetic fields below the saturation field.
HST observation of the inner coma of 2060 chiron
1995
Abstract The analysis of persistent comae of very large and distant comets allows us to infer the poorly known physical properties of dust and icy grains produced beyond Jupiter. Chiron is particularly interesting because Fulle ( Astron. Astrophys. 282 , 980–988; 1994) has shown that the strong asymmetricity of its coma (West, Astron. Astrophys. 241 , 635–645 1991) allows us to infer rotational properties of Chiron's nucleus. In this paper we report the observation of the asymmetric inner coma of Chiron from the analysis of 44 images of Chiron and eight images of a standard star available from the HST archive. The images were taken during February/March 1993, when Ch iron was 9.3 AU from th…
Structure of longitudinal chromomagnetic fields in high energy collisions
2014
We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.
