Homogenenous Multitype Fragmentations
Jean Bertoin
A homogeneous mass-fragmentation, as it has been defined in \cite{RFC}, describes the evolution of the collection of masses of fragments of an object which breaks down into pieces…
Stratification in P2P Networks - Application to BitTorrent
Anh-Tuan Gai, Fabien Mathieu, Julien Reynier +1
We introduce a model for decentralized networks with collaborating peers. The model is based on the stable matching theory which is applied to systems with a global ranking utility…
Ultrahigh finesse Fabry-Perot superconducting resonator
Stefan Kuhr, Sébastien Gleyzes, Christine Guerlin +10
We have built a microwave Fabry-Perot resonator made of diamond-machined copper mirrors coated with superconducting niobium. Its damping time (Tc = 130 ms at 51 GHz and 0.8 K) corr…
Spinor-Vector Duality in fermionic Z2XZ2 heterotic orbifold models
Alon E. Faraggi, Costas Kounnas, John Rizos
We continue the classification of the fermionic Z2XZ2 heterotic string vacua with symmetric internal shifts. The space of models is spanned by working with a fixed set of boundary…
Effective creases and contact angles between membrane domains with high spontaneous curvature
Jean-Baptiste Fournier, Martine Ben Amar
We show that the short-scale elastic distortions that are excited in the vicinity of the joint between different lipidic membrane domains (at a scale of \~10 nm) may produce a "cre…
Eikonal Approximation in AdS/CFT: Conformal Partial Waves and Finite N Four-Point Functions
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We introduce the impact-parameter representation for conformal field theory correlators of the form A ~ < O_1 O_2 O_1 O_2 >. This representation is appropriate in the eikonal kinem…
