Competition between hidden order and antiferromagnetism in URu_2Si_2 under uniaxial stress studied by neutron scattering [PDF]

open access: yes, 2005
We have performed elastic neutron scattering experiments under uniaxial stress sigma applied along the tetragonal [100], [110] and [001] directions for the heavy electron compound URu2Si2.

Tetra­butyl­ammonium tris­(methyl­sulfanylmeth­yl)phenyl­borate [PDF]

open access: yes, 2009
In the title molecular salt, C16H36N+·C12H20BS3-, three of the four n-butyl chains show a trans conformation, whereas the fourth has the C—C—C—C torsion angle in a gauche conformation [-77.8 (5)°]. In the crystal, mol­ecules are packed in layers parallel

Brane singularities with mixtures in the bulk [PDF]

open access: yes, 2012
By extending previous analysis of the authors, a systematic study of the singularity structure and possible asymptotic behaviors of five-dimensional braneworld solutions is performed in the case where the bulk is a mixture of an analog of perfect fluid ...

Necessary and Sufficient Elastic Stability Conditions in Various Crystal Systems

open access: yes, 2014
While the Born elastic stability criteria are well-known for cubic crystals, there is some confusion in the literature about the form it should take for lower symmetry crystal classes.

Birkhoff's Theorem for Three-Dimensional AdS Gravity

open access: yes, 2004
All three-dimensional matter-free spacetimes with negative cosmological constant, compatible with cyclic symmetry are identified. The only cyclic solutions are the 2+1 (BTZ) black hole with SO(2) x R isometry, and the self-dual Coussaert-Henneaux ...
