On the nature of X-Ray Flashes
C. Barraud, F. Daigne, R. Mochkovitch +1
We discuss the origin of X-Ray Flashes (XRFs), a recently discovered class of Gamma-Ray Bursts (GRBs). Using a simplified model for internal shocks we check if XRFs can be intrinsi…
Cross-over between first-order and critical wetting at the liquid-vapour interface of n-alkane/methanol mixtures: tricritical wetting and critical prewetting
A. I. Posazhennikova, J. O. Indekeu, D. Ross +2
A mean-field theory is presented which describes the basic observations of recent experiments revealing rich wetting behaviour of n-alkane/methanol mixtures at the liquid-vapour in…
Validity of the Hohenberg Theorem for a Generalized Bose-Einstein Condensation in Two Dimensions
W. J. Mullin, M. Holzmann, F. Laloe
Several authors have considered the possibility of a generalized Bose-Einstein condensation (BEC) in which a band of low states is occupied so that the total occupation number is m…
Crashes as Critical Points
Anders Johansen, Olivier Ledoit, Didier Sornette
We study a rational expectation model of bubbles and crashes. The model has two components : (1) our key assumption is that a crash may be caused by local self-reinforcing imitatio…
