Unified Solution of the Expected Maximum of a Random Walk and the Discrete Flux to a Spherical Trap
Satya N. Majumdar, Alain Comtet, Robert M. Ziff
Two random-walk related problems which have been studied independently in the past, the expected maximum of a random walker in one dimension and the flux to a spherical trap of par…
Contribution to the modeling of a liquid film flowing down inside a vertical circular tube
Samuel Ndoumbe, François Lusseyran, Boujema Izrar
This note focuses on the development of a 2D model of a thin liquid film flowing down inside a vertical pipe. This model is based on the large wavelength assumption and valid for h…
Observation of dipole-dipole interaction in a degenerate quantum gas
J. Stuhler, A. Griesmaier, T. Koch +5
We have investigated the expansion of a Bose-Einstein condensate (BEC) of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads…
Path decompositions for real Levy processes
Thomas Duquesne
Let be a real Lévy process and let $\Xpos $ be the process conditioned to stay positive. We assume that is regular for and with respect to…
Fluctuations of internal energy flow in a vibrated granular gas
A. Puglisi, P. Visco, A. Barrat +2
The non-equilibrium fluctuations of power flux in a fluidized granular media have been recently measured in an experiment [Phys. Rev. Lett. 92, 164301, 2004], which was announced t…
Injected power and entropy flow in a heated granular gas
P. Visco, A. Puglisi, A. Barrat +2
Our interest goes to the power injected in a heated granular gas and to the possibility to interpret it in terms of entropy flow. We numerically determine the distribution of the i…
