Properties of Flares-Generated Seismic Waves on the Sun
A. G. Kosovichev
The solar seismic waves excited by solar flares (``sunquakes'') are observed as circular expanding waves on the Sun's surface. The first sunquake was observed for a flare of July 9…
A Tunable Anomalous Hall Effect in a Non-Ferromagnetic System
J. Cumings, L. S. Moore, H. T. Chou +4
We measure the low-field Hall resistivity of a magnetically-doped two-dimensional electron gas as a function of temperature and electrically-gated carrier density. Comparing these…
Measurements of the branching fractions and CP-asymmetries of B- --> D0_(CP) K- decays
The BABAR Collaboration, B. Aubert
We present a study of the decay B- --> D0_(CP) K- and its charge conjugate, where D0_(CP) is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 2…
Gauge-Mediated Supersymmetry Breaking in String Compactifications
Duiliu-Emanuel Diaconescu, Bogdan Florea, Shamit Kachru +1
We provide string theory examples where a toy model of a SUSY GUT or the MSSM is embedded in a compactification along with a gauge sector which dynamically breaks supersymmetry. We…
Thermal Conductance of an Individual Single-Wall Carbon Nanotube above Room Temperature
Eric Pop, David Mann, Qian Wang +2
The thermal properties of a suspended metallic single-wall carbon nanotube (SWNT) are extracted from its high-bias (I-V) electrical characteristics over the 300-800 K temperature r…
Low temperature structural phase transition and incommensurate lattice modulation in the spin gap compound BaCuSi2O6
E. C. Samulon, Z. Islam, S. E. Sebastian +4
Results of high resolution x-ray diffraction experiments are presented for single crystals of the spin gap compound BaCuSiO in the temperature range from 16 to 300 K. The d…
