Omitting types and AF algebras
Kevin Carlson, Enoch Cheung, Ilijas Farah +5
We give model-theoretic characterizations of UHF algebras and of AF algebras as C*-algebras that omit certain sets of types.
Dynamical age differences among coeval star clusters as revealed by blue stragglers
F. R. Ferraro, B. Lanzoni, E. Dalessandro +11
Globular star clusters that formed at the same cosmic time may have evolved rather differently from a dynamical point of view (because that evolution depends on the internal enviro…
Is γ-ray emission from novae affected by interference effects in the 18F(p,α)15O reaction?
A. M. Laird, A. Parikh, A. St. J. Murphy +14
The 18F(p,α)15O reaction rate is crucial for constraining model predictions of the γ-ray observable radioisotope 18F produced in novae. The determination of this rate is challengin…
Mixture Model Averaging for Clustering
Yuhong Wei, Paul D. McNicholas
In mixture model-based clustering applications, it is common to fit several models from a family and report clustering results from only the `best' one. In such circumstances, sele…
Incommensurability Effects in Odd Length J_1-J_2 Quantum Spin Chains: On-site magnetization and Entanglement
Andreas Deschner, Erik S. Sørensen
For the antiferromagnetic J_1-J_2 quantum spin chain with an even number of sites, the point J_2^d=1/2 J_1 is a disorder point. It marks the onset of incommensurate real space corr…
Bloch Oscillations of Cold Atoms in a Cavity: Effects of Quantum Noise
B. Prasanna Venkatesh, D. H. J. O'Dell
We extend our theory of Bloch oscillations of cold atoms inside an optical cavity [ Venkatesh et al. Phys. Rev. A 80 063834 (2009)] to include the effects of quantum noise arising…
