Excitation spectra and ground state properties of the layered spin-1/2 frustrated antiferromagnets Cs_2CuCl_4 and Cs_2CuBr_4
John O. Fjaerestad, Weihong Zheng, Rajiv R. P. Singh +2
We use series expansion methods to study ground- and excited-state properties in the helically ordered phase of spin-1/2 frustrated antiferromagnets on an anisotropic triangular la…
Charge density of a positively charged vector boson may be negative
Victor Flambaum, Michael Kuchiev
The charge density of vector particles, for example W, may change sign. The effect manifests itself even for a free propagation; when the energy of the W-boson is higher than sqrt{…
Strength of convergence and multiplicities in the spectrum of a C*-dynamical system
Robert Archbold, Astrid an Huef
We consider separable -dynamical systems for which the induced action of the group on the spectrum of the -algebra is free. We study how the re…
Revision of VLT/UVES constraints on a varying fine-structure constant
Michael T. Murphy, John K. Webb, Victor V. Flambaum
We critically review the current null results on a varying fine-structure constant, alpha, derived from VLT/UVES quasar absorption spectra, focusing primarily on the many-multiplet…
The Metallicity of Stars with Close Companions
Daniel Grether, Charles H. Lineweaver
We examine the relationship between the frequency of close companions (stellar and planetary companions with orbital periods < 5 years) and the metallicity of their Sun-like (~ FGK…
Lyapunov Modes for a Nonequilibrium System with a Heat Flux
Tooru Taniguchi, Gary P. Morriss
We present the first numerical observation of Lyapunov modes (mode structure of Lyapunov vectors) in a system maintained in a nonequilibrium steady state. The modes show some simil…
