Local morphisms and modules with a semilocal endomorphism ring
Alberto Facchini, Dolors Herbera
An associative ring with 1 is said to be semilocal provided it is semisimple artinian modulo its Jacobson radical, that is, modulo its Jacobson radical it is isomorphic to a finite…
A not so simple local multiplier algebra
Pere Ara, Martin Mathieu
We construct an AF-algebra such that its local multiplier algebra does not agree with , thus answering a question raised…
Comment on "Earthquakes Descaled"
Alvaro Corral, Kim Christensen
We show that Bak et al.'s unified scaling law cannot be trivially explained by a single Omori aftershock sequence. On the contrary, the spatial heterogeneity of seismicity plays a…
The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
Optimal phase measurements with pure Gaussian states
Alex Monras
We analyze the Heisenberg limit on phase estimation for Gaussian states. In the analysis, no reference to a phase operator is made. We prove that the squeezed vacuum state is the m…
Splitting and merging an elongated Bose-Einstein condensate at finite temperature
A. Mebrahtu, A. Sanpera, M. Lewenstein
We analyze coherence effects during the splitting of a quasi one-dimensional condensate into two spatially separated ones and their subsequent merging into a single condensate. Our…
