Asymptotic dynamic for dipolar Quantum Gases below the ground state energy threshold

We consider the Gross-Pitaevskii equation describing a dipolar Bose-Einstein condensate without external confinement. We first consider the unstable regime, where the nonlocal nonlinearityis neither positive nor radially symmetric and standing states are k ...

Microlensing of the broad line region in 17 lensed quasars

Frédéric Courbin, Georges Meylan

When an image of a strongly lensed quasar is microlensed, the different components of its spectrum are expected to be differentially magnified owing to the different sizes of the corresponding emitting region. Chromatic changes are expected to be observed ...

Horizontal mixing in lakes

Alfred Johny Wüest

Horizontal mixing in the upper hypolimnion of lakes far from the boundaries was studied in lake basins with surface areas between 5 and 220 km(2) by observing the growth of the concentration distribution of the fluorescent dye sodium fluorescein (uranin). ...

Stability and instability of expanding solutions to the Lorentzian constant-positive-mean-curvature flow

Willie Wai Yeung Wong

We study constant mean curvature Lorentzian hypersurfaces of R^{1,d+1} from the point of view of its Cauchy problem. We completely classify the spherically symmetric solutions, which include among them a manifold isometric to the de Sitter space of general ...
