Wave fronts may move upstream in semiconductor superlattices
In weakly coupled, current biased, doped semiconductor superlattices, domain walls may move upstream against the flow of electrons. For appropriate doping values, a domain wall separating two electric-field domains moves downstream below a first critical current, it remains stationary between this value and a second critical current, and then moves upstream above. These conclusions are reached ...
متن کاملVolcanic Ash and Daily Mortality in Sweden after the Icelandic Volcano Eruption of May 2011
In the aftermath of the Icelandic volcano Grimsvötn's eruption on 21 May 2011, volcanic ash reached Northern Europe. Elevated levels of ambient particles (PM) were registered in mid Sweden. The aim of the present study was to investigate if the Grimsvötn eruption had an effect on mortality in Sweden. Based on PM measurements at 16 sites across Sweden, data were classified into an ash exposed da...
متن کاملStructure of Stationary Photodissociation Fronts
The structure of stationary photodissociation fronts is revisited. H 2 self-shielding is discussed, including the eeects of line overlap. We nd that line overlap is important for N(H 2) > 10 20 cm ?2 , with a factor-of-two suppression of pumping rates at column densities N(H 2) 3 10 20 cm ?2. We compute multiline UV pumping models, and compare these with simple analytic approximations for the e...

The structure of stationary photodissociation fronts is revisited. H2 self-shielding is discussed, including the effects of line overlap. We find that line overlap is important for N(H2) ∼> 1020 cm−2, with a factor-of-two suppression of pumping rates at column densities N(H2) ≈ 3 × 1020 cm−2. We compute multiline UV pumping models, and compare these with simple analytic approximations for the e...
متن کاملStability of Stationary Fronts in a Non-linear Wave Equation with Spatial Inhomogeneity
We consider inhomogeneous non-linear wave equations of the type utt = uxx + V ′(u, x)− αut (α ≥ 0). The spatial real axis is divided in intervals Ii, i = 0, . . . , N + 1 and on each individual interval the potential is homogeneous, i.e., V (u, x) = Vi(u) for x ∈ Ii. By varying the lengths of the middle intervals, typically one can obtain large families of stationary front or solitary wave solu...
