Experimental realization of a relativistic fluxon ratchet
G. Carapella, G. Costabile, R. Latempa +4
We report the observation of the ratchet effect for a relativistic flux quantum trapped in an annular Josephson junction embedded in an inhomogeneous magnetic field. In such a soli…
Two Dimensional Conformal Field Theory on Open and Unoriented Surfaces
Yassen S. Stanev
Introduction to two dimensional conformal field theory on open and unoriented surfaces. The construction is illustrated in detail on the example of SU(2) WZW models.
CMB Polarization: Scientific Case and Data Analysis Issues
A. Balbi, P. Cabella, G. de Gasperis +2
We review the science case for studying CMB polarization. We then discuss the main issues related to the analysis of forth-coming polarized CMB data, such as those expected from ba…
What's Behind Acoustic Peaks in the Cosmic Microwave Background Anisotropies
C. Baccigalupi, A. Balbi, S. Matarrese +2
We give a brief review of the physics of acoustic oscillations in Cosmic Microwave Background (CMB) anisotropies. As an example of the impact of their detection in cosmology, we sh…
On the primordial helium content: CMB and stellar constraints
G. Bono, A. Balbi, S. Cassisi +2
We present the results of a joint investigation aimed at constraining the primordial He content () on the basis of both the Cosmic Microwave Background (CMB) anisotropy and tw…
Descent Representations and Multivariate Statistics
Ron M. Adin, Francesco Brenti, Yuval Roichman
Combinatorial identities on Weyl groups of types and are derived from special bases of the corresponding coinvariant algebras. Using the Garsia-Stanton descent basis of the…
