Polarization multistability of cavity polaritons
N. A. Gippius, I. A. Shelykh, D. D. Solnyshkov +5
New effects of polarization multistability and polarization hysteresis in a coherently driven polariton condensate in a semiconductor microcavity are predicted and theoretically an…
Simultaneous multiwavelength observations of the Low/Hard State of the X-ray transient source SWIFT J1753.5-0127
M. Cadolle Bel, M. Ribo, J. Rodriguez +11
We report the results of simultaneous multiwavelength observations of the X-ray transient source SWIFT J1753.5-0127 performed with INTEGRAL, RXTE, NTT, REM and VLA on 2005 August 1…
High sensitivity low frequency radio observations of cD galaxies
S. Giacintucci, T. Venturi, S. Bardelli +3
We present the GMRT 235 MHz images of three radio galaxies and 610 MHz images of two sources belonging to a complete sample of cD galaxies in rich and poor galaxy clusters. The ana…
Embeddings of submanifolds and normal bundles
Marco Abate, Filippo Bracci, Francesca Tovena
This paper is devoted to the study of the embeddings of a complex submanifold inside a larger complex manifold ; in particular, we are interested in comparing the embedding…
Electromagnetic form factors of the nucleon in spacelike and timelike regions
J. P. B. C. de Melo, T. Frederico, E. Pace +2
An approach for a unified description of the nucleon electromagnetic form factors in spacelike and timelike regions is presented. The main ingredients of our model are: a Mand…
Multi-scale model of gradient evolution in turbulent flows
Luca Biferale, Laurent Chevillard, Charles Meneveau +1
A multi-scale model for the evolution of the velocity gradient tensor in fully developed turbulence is proposed. The model is based on a coupling between a ``Restricted Euler'' dyn…
The exotic chemical composition of the Sagittarius dwarf Spheroidal galaxy
L. Sbordone, P. Bonifacio, R. Buonanno +3
The Sagittarius dwarf Spheroidal galaxy is the nearest neighbor of the Milky Way. Moving along a short period quasi-polar orbit within the Halo, it is being destroyed by the tidal…
Electronic screening and correlated superconductivity in carbon nanotubes
S. Bellucci, M. Cini, P. Onorato +1
A theoretical analysis of the superconductivity observed recently in Carbon nanotubes is proposed. We argue that ultra-small (diameter ) single wall carbon nanotubes…
Order in the Chaos: Spin-up and Spin-down during the 2002 Outburst of SAX J1808.4-3658
L. Burderi, T. Di Salvo, M. T. Menna +2
We present a timing analysis of the 2002 outburst of the accreting millisecond pulsar SAX J1808.4-3658. A study of the phase delays of the entire pulse profile shows a behavior tha…
Strict weak mixing of some C*-dynamical systems based on free shifts
Francesco Fidaleo, Farrukh Mukhamedov
We define a stronger property than unique ergodicity with respect to the fixed-point subalgebra previously investigated by Abadie and Dykema. Such a property is denoted as F-strict…
On Cardy states in the (2,2,2,2) Gepner model
Gor Sarkissian
We study Cardy states in the (2,2,2,2) Gepner model from the algebraic and geometric sides. We present the full list of primaries of this model together with their characters. The…
The HELLAS2XMM survey.VIII. Optical identifications of the extended sample
F. Cocchia, F. Fiore, C. Vignali +14
(Abridged) We present the results of the photometric and spectroscopic identification of 110 hard X-ray selected sources (6e-15<F(2-10 keV)<4e-14 cgs) from 5 additional XMM-Newton…
Timing of the Accreting Millisecond Pulsar XTE J1814-338
A. Papitto, T. Di Salvo, L. Burderi +3
We present a precise timing analysis of the accreting millisecond pulsar XTE J1814-338 during its 2003 outburst, observed by RXTE. A full orbital solution is given for the first ti…
Chameleon effect, the range of values hypothesis and reproducing the EPR-Bohm correlations
Luigi Accardi, Andrei Khrennikov
We present a detailed analysis of assumptions that J. Bell used to show that local realism contradicts QM. We find that Bell's viewpoint on realism is nonphysical, because it impli…
Orbits of real forms in complex flag manifolds
Andrea Altomani, Costantino Medori, Mauro Nacinovich
We study, from the point of view of CR geometry, the orbits M of a real form G of a complex semisimple Lie group G in a complex flag manifold G/Q. In particular we characterize tho…
Pure Spinor Strings in TsT Deformed Background
P. A. Grassi, J. Kluson
We consider pure spinor strings that propagate in the background generated by a sequence of TsT transformations. We use the fact that U(1) isometry variables of TsT-transformed bac…
Timing an Accreting Millisecond Pulsar: Measuring the Accretion Torque in IGR J00291+5934
L. Burderi, T. Di Salvo, G. Lavagetto +7
We performed a timing analysis of the fastest accreting millisecond pulsar IGR J00291+5934 using RXTE data taken during the outburst of December 2004. We corrected the arrival time…
Generalized Lattice Boltzmann Method with multi-range pseudo-potential
M. Sbragaglia, R. Benzi, L. Biferale +3
The physical behaviour of a class of mesoscopic models for multiphase flows is analyzed in details near interfaces. In particular, an extended pseudo-potential method is developed,…
Eikonal Approximation in AdS/CFT: From Shock Waves to Four-Point Functions
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We initiate a program to generalize the standard eikonal approximation to compute amplitudes in Anti-de Sitter spacetimes. Inspired by the shock wave derivation of the eikonal ampl…
