Expression of the nucleon-nucleon interaction to order 1/NC in terms of Fermi Invariants allows a dynamical interpretation of the interaction and leads to a consistent construction of the associated interaction currents to order 1/NC . The numerically significant components of 4 different modern realistic phenomenological interaction models are shown to admit very similar meson exchange interpr...

One of the goals of NASA’s Fermi Gamma-ray Space Telescope (formerly GLAST) will be the detection of gamma rays from dark-matter annihilation in the Galactic halo. Theoretical arguments suggest that dark matter may be bound into subhalos with masses as small as 10 –10M . If so, it may be possible to detect individual subhalos as point sources in the Fermi Telescope. It has further been argued t...

We consider d=10 N=1 supersymmetry algebra with maximal number of tensor charges Z and introduce a class of orbits of Z, invariant w.r.t. the T8 subgroup of massless particles’ little group T8 ⋉ SO(8). For that class of orbits we classify all possible orbits and little groups, which appear to be semidirect products of T8 ⋉ SO(k1) × ...SO(kn) form, with k1 + ... + kn = 8, where compact factor is...

Using operator algebraic methods we show that the moment generating function of charge transport in a system with infinitely many non-interacting Fermions is given by a determinant of a certain operator in the one-particle Hilbert space. The formula is equivalent to a formula of Levitov in the finite dimensional case and may be viewed as its regularized form in general. Our result embodies two ...

Small-amplitude waves in the Fermi-Pasta-Ulam (FPU) lattice with weakly anharmonic interaction potentials are described by the generalized Korteweg-de Vries (KdV) equation. Justification of the small-amplitude approximation is usually performed on the time scale, for which dynamics of the KdV equation is defined. We show how to extend justification analysis on longer time intervals provided dyn...

We investigated the effects of laser wavelength on the atomic, ionic, and radiative emission from laser-produced tin plasmas. For generating plasmas, planar tin targets were excited using either high intensity neodymium-doped yttrium aluminum garnet Nd:YAG, 1.06 m or carbon dioxide CO2, 10.6 m laser pulses; both are considered to be potential excitation lasers for an extreme ultraviolet EUV lit...

Over the last several years we have predicted and observed plasmas with an index of refraction greater than 1 in the soft X-ray regime. These plasmas are usually a few times ionized and have ranged from lowZ carbon plasmas to mid-Z tin plasmas. Our main calculational tool has been the average-atom code. We have recently observed C2þ plasmas with an index of refraction greater than 1 at a wavele...
