We discuss the spontaneous compactification of chiral N = 2 ten-dimensional supergravity from ten to five dimensions on S/sup 5/. Harmonic analysis on S/sup 5/ is used to compute the complete mass… Expand

We present first results from a Chandra X-Ray Observatory observation of the radio galaxy Centaurus A with the High-Resolution Camera. All previously reported major sources of X-ray emission… Expand

A perturbative method is developed to calculate the finite size corrections of the low lying energies of the asymmetric XXZ hamiltonian near the stochastic line. The crossover from isotropic to… Expand

A new non-Abelian gauge group which becomes strong at ${10}^{8}$\char21{}${10}^{12}$ GeV is suggested for a confining force of a composite invisible axion. This scheme naturally explains why the… Expand

The expansion method by a time-dependent basis of the eigenfunctions for the space-coordinate-dependent sub-Hamiltonian is one of the most natural frameworks for quantum systems, relativistic as well… Expand

It is shown that the weak states which are used in the standard treatment of neutrino oscillations do not, in general, describe correctly the neutrinos produced and detected in weak-interaction… Expand

Recently several methods have been proposed for generation of superposition (Schrodinger-cat) states in microwave cavities. At microwave frequencies, thermal photons can significantly affect… Expand
