A Raman approach to quantum logic in Calcium-like ions
Mark S. Gulley, Andrew G. White, Daniel F. V. James
We consider the feasibility of performing quantum logic operations based on stimulated Raman transitions in trapped Calcium ions. This technique avoids many of the technical diffic…
Highly Ionized Absorption in the X-ray Spectrum of Cyg X-1
H. L. Marshall, N. S. Schulz, T. Fang +4
Using the Chandra High Energy Transmission Grating Spectrometer (HETGS), we have found significant absorption features in the X-ray spectrum of Cyg X-1 taken in the continuous cloc…
O(a) improved QCD: The 3-loop beta-function, and the critical hopping parameter
A. Bode, H. Panagopoulos, Y. Proestos
We calculate the 3-loop bare -function of QCD, formulated on the lattice with the clover fermionic action. The dependence of our result on the number of colors , the number o…
Rotation of the solar interior
J. Christensen-Dalsgaard, M. J. Thompson
Helioseismology has allowed us to infer the rotation in the greater part of the solar interior with high precision and resolution. The results show interesting conflicts with earli…
SOLA inversions for the core structure of solar-type stars
Sarbani Basu, J. Christensen-Dalsgaard, M. J. Thompson
The Subtractive Optimally Localized Averages (SOLA) method, developed and extensively used in helioseismology, is applied to artificial data to obtain measures of the sound speed i…
Asteroseismic Inference for Solar-Type Stars
M. J. P. F. G. Monteiro, J. Christensen-Dalsgaard, M. J. Thompson
The oscillation spectra of solar-type stars may in the not-too- distant future be used to constrain certain properties of the stars. The CD diagram of large versus small frequency…
