Granular media: some ideas from statistical physics

J-P Bouchaud

These lecture notes cover the statics and glassy dynamics of granular media. Most of the lectures were in fact devoted to `force propagation' models. We discuss the experimental an…

Directed and Elliptic Flow in Pb+Pb collisions at 40 and 158 AGeV

Alexander Wetzler, N. Borghini, P. M. Dinh +4

Directed and elliptic flow are reported for charged pions and protons as a function of transverse momentum, rapidity, and centrality in 40 and 158 AGeV Pb + Pb collisions. The stan…

The XMM-Newton view of the Galactic Centre

Masaaki Sakano, Robert S. Warwick, Anne Decourchelle

In X-rays, the Galactic Centre (GC) Region appears as a complex of diffuse thermal and non-thermal X-ray emission intermixed with a population of luminous discrete sources. Here we…

The Nature of the Low-Metallicity ISM in the Dwarf Galaxy NGC 1569

F. Galliano, S. C. Madden, A. P. Jones +3

We are modeling the spectra of dwarf galaxies from infrared to submillimeter wavelengths to understand the nature of the various dust components in low-metallicity environments, wh…

The cosmological constant and general isocurvature initial conditions

R. Trotta, A. Riazuelo, R. Durrer

We investigate in detail the question whether a non-vanishing cosmological constant is required by present-day cosmic microwave background and large scale structure data when gener…

QCD and Nuclei

Mannque Rho

I discuss how the fundamental theory of strong interactions given by QCD can be exploited to make accurate predictions for the solar fusion processes involving few-nucleon systems…

Theoretical study of the finite temperature spectroscopy in van der Waals clusters. III Solvated Chromophore as an effective diatomics

F. Calvo, F. Spiegelman, J. M. Mestdagh

The absorption spectroscopy of calcium-doped argon clusters is described in terms of an effective diatomics molecule Ca-(Ar_n), in the framework of semiclassical vertical transitio…

Diphasic non-local model for granular surface flows

D. Bonamy, P. Mills

Considering recent results revealing the existence of multi-scale rigid clusters of grains embedded in granular surface flows, i.e. flows down an erodible bed, we describe here the…

Asymmetric evolving random networks

Stephane Coulomb, Michel Bauer

We generalize the poissonian evolving random graph model of Bauer and Bernard to deal with arbitrary degree distributions. The motivation comes from biological networks, which are…

Variational charge renormalization in charged systems

Roland R. Netz, Henri Orland

We apply general variational techniques to the problem of the counterion distribution around highly charged objects where strong condensation of counterions takes place. Within a f…

Characteristic Polynomials of Complex Random Matrix Models

G. Akemann, G. Vernizzi

We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogona…

An influence functional for ultrasoft QCD

F. Guerin, E. Iancu

A real-time path integral for ultrasoft QCD is formulated. It exhibits a Feynman's influence functional. The statistical properties of the theory and the gauge symmetry are explici…
