Small-scale anisotropy and intermittency in high and low-latitude solar wind
A. Bigazzi, L. Biferale, S. M. A. Gama +1
We analyze low and high--latitude fast solar wind data from the Ulysses spacecraft from 1992 to 1994 using a a systematic method to analyse the anisotropic content of the magnetic…
UVES observations of the Canis Major overdensity
L. Sbordone, P. Bonifacio, G. Marconi +2
We present the first detailed chemical abundances for three giant stars which are candidate members of the Canis Major overdensity, obtained by using FLAMES-UVES at VLT. The stars,…
Homotopy of posets, net-cohomology and superselection sectors in globally hyperbolic spacetimes
Giuseppe Ruzzi
We study sharply localized sectors, known as sectors of DHR-type, of a net of local observables, in arbitrary globally hyperbolic spacetimes with dimension . We show that t…
A Construction of Coxeter Group Representations (II)
Ron M. Adin, Francesco Brenti, Yuval Roichman
An axiomatic approach to the representation theory of Coxeter groups and their Hecke algebras was presented in [1]. Combinatorial aspects of this construction are studied in this p…
A quantum duality principle for coisotropic subgroups and Poisson quotients
Nicola Ciccoli, Fabio Gavarini
We develop a quantum duality principle for coisotropic subgroups of a (formal) Poisson group and its dual. Namely, starting from a quantum coisotropic subgroup (for a quantization…
Extension of the structure theorem of Borchers and its application to half-sided modular inclusions
H. Araki, L. Zsido
A result of H.-W. Wiesbrock is extended from the case of a common cyclic and separating vector for the half-sided modular inclusion of von Neumann algebras to the case of a common…
Tracing the Warm Hot Intergalactic Medium in the local Universe
M. Viel, E. Branchini, R. Cen +4
We present a simple method for tracing the spatial distribution and predicting the physical properties of the Warm-Hot Intergalactic Medium (WHIM), from the map of galaxy light in…
Measurement of the leptonic decay widths of the phi-meson with the KLOE detector
F. Ambrosino
The phi-meson leptonic widths, Gee and Gmm, are obtained, respectively, from the e+e- forward-backward asymmetry and the muon cross section around the phi-mass energy. We find Gee=…
The soft X-ray counterpart of the newly discovered INTEGRAL source IGRJ16195-4945
L. Sidoli, S. Vercellone, S. Mereghetti +1
The INTEGRAL satellite, during its regular scanning observations of the Galactic plane, has discovered several new X-ray sources emitting above 20 keV. The nature of the great majo…
The Duty-cycle of Gamma-ray Blazars: a New Approach, New Results
S. Vercellone, S. Soldi, A. W. Chen +1
We study several properties of blazars detected in the gamma-ray energy range by comparing the EGRET sources with a sample of radio blazars which can be considered possible gamma-r…
KMS states and the chemical potential for disordered systems
Francesco Fidaleo
We extend the theory of the chemical potential associated to a compact separable gauge group to the case of disordered quantum systems. This is done in the natural framework of ope…
VINCI-VLTI measurements of HR 4049: the physical size of the circumbinary envelope
Simone Antoniucci, Francesco Paresce, Markus Wittkowski
We present the first detection of the envelope which surrounds the post-AGB binary source HR 4049. VINCI-VLTI K-band interferometric observations of this source imply the existence…
Ritt's theorem and the Heins map in hyperbolic complex manifolds
Marco Abate, Filippo Bracci
Let X be a Kobayashi hyperbolic complex manifold, and assume that X does not contain compact complex submanifolds of positive dimension (e.g., X Stein). We shall prove the followin…
W=0 pairing in Hubbard and related models of low-dimensional superconductors
Adalberto Balzarotti, Michele Cini, Enrico Perfetto +1
Lattice Hamiltonians with on-site interaction have W=0 solutions, that is, many-body {\em singlet} eigenstates without double occupation. In particular, W=0 pairs give a clue t…
Inhomogeneous Anisotropic Passive Scalars
M. Martins Afonso, M. Sbragaglia
We investigate the behaviour of the two-point correlation function in the context of passive scalars for non homogeneous, non isotropic forcing ensembles. Exact analytical computat…
Microscopic Model for a Strongly Correlated Superconducting Single-Electron-Transistor
Enrico Perfetto, Michele Cini
We model a Superconducting Single-Electron Transistor operating by repulsive interactions. The device consists of a ring of Hubbard clusters, placed between electrodes and capaciti…
Dynamical scaling and intermittency in shell models of turbulence
R. Benzi, L. Biferale, M. Sbragaglia
We introduce a model for the turbulent energy cascade aimed at studying the effect of dynamical scaling on intermittency. In particular, we show that by slowing down the energy tra…

Fabio Gavarini, Zoran Rakic
Let U_q(sl_2) be the standard Drinfeld-Jimbo quantized universal enveloping algebra over sl_2, let F_q[SL_2] be the corresponding quantum function algebra, and let R be the ring of…
