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.
Characterizing the atomic mass surface beyond the proton drip line via a-decay measurements of the s1/2 ground state of 165Re and the h11/2 isomer in 161Ta
D. O'Donnell, R. D. Page, C. Scholey +33
The a-decay chains originating from the s1/2 and h11/2 states in 173Au have been investigated following fusion-evaporation reactions. Four generations of a radioactivities have bee…
Neutron-star mergers in scalar-tensor theories of gravity
Enrico Barausse, Carlos Palenzuela, Marcelo Ponce +1
Scalar-tensor theories of gravity are natural phenomenological alternatives to General Relativity, where the gravitational interaction is mediated by a scalar degree of freedom, be…
Slowly rotating black holes in Horava-Lifshitz gravity
Enrico Barausse, Thomas P. Sotiriou
In a recent paper we claimed that there there are no slowly rotating, stationary, axisymmetric black holes in the infrared limit of Horava-Lifshitz gravity, provided that they are…
Self-Dual Maps and Symmetric Bistochastic Matrices
Corey O'Meara, Rajesh Pereira
The H-unistochastic matrices are a special class of symmetric bistochastic matrices obtained by taking the square of the absolute value of each entry of a Hermitian unitary matrix.…
Optical Signatures of the Tunable Band Gap and Valley-Spin Coupling in Silicene
Lukas Stille, Calvin J. Tabert, Elisabeth J. Nicol
We investigate the optical response of the silicene and similar materials, such as germanene, in the presence of an electrically tunable band gap for variable doping. The interplay…
