Record dynamics and the observed temperature plateau in the magnetic creep rate of type II superconductors
L. P. Oliveira, Henrik Jeldtoft Jensen, Mario Nicodemi +1
We use Monte Carlo simulations of a coarse grained three dimensional model to demonstrate that the experimentally observed approximate temperature independence of the magnetic cree…
Moment Formulas For The Quasi-Nilpotent DT-Operator
L. Aagaard, U. Haagerup
Let T be the quasi-nilpotent DT-operator. By use of Voiculescu's amalgamated R-transform we compute the moments of , where , and the Brown-measure o…
The Inner Amenability of the Generalized Thompson Group
Gabriel Picioroaga
In this paper we prove that the general version, F(N) of the Thompson group is inner amenable. As a consequence we generalize a result of P.Jolissaint. To do so, we prove first tha…
On the universal property of Pimsner-Toeplitz C*-algebras and their continuous analogues
Ilan Hirshberg
We consider C*-algebras generated by a single Hilbert bimodule (Pimsner-Toeplitz algebras) and by a product systems of Hilbert bimodules. We give a new proof of a theorem of Pimsne…
AF-embeddings into C*-algebras of real rank zero
Francesc Perera, Mikael Rordam
It is proved that every separable -algebra of real rank zero contains an AF-sub--algebra such that the inclusion mapping induces an isomorphism of the ideal lattices of t…
Neutrino physics from cosmology
Steen Hannestad
Cosmological observations have in the past few years become an increasingly powerful method for determining parameters within the neutrino sector, such as the presence of sterile s…
