Energy losses of fast heavy-ion projectiles in dense hydrogen plasmas
D. Ballester, I. M. Tkachenko
It has been recently shown that the Bethe-Larkin formula for the energy losses of fast heavy-ion projectiles in dense hydrogen plasmas is corrected by the electron-ion correlations…
On maximal Subgroups of the multiplicative group of a division algebra
R. Hazrat, A. R. Wadsworth
The question of existence of a maximal subgroup in the multiplicative group D* of a division algebra D finite dimensional over its center F is investigated. We prove that if D* has…
Stable isomorphism of dual operator spaces
G. K. Eleftherakis, V. I. Paulsen, I. G. Todorov
We prove that two dual operator spaces and are stably isomorphic if and only if there exist completely isometric normal representations and of and , respecti…
Discrete solitons and vortices in hexagonal and honeycomb lattices: Existence, stability, and dynamics
K. J. H. Law, P. G. Kevrekidis, V. Koukouloyannis +3
We consider a prototypical dynamical lattice model, namely, the discrete nonlinear Schroedinger equation on nonsquare lattice geometries. We present a systematic classification of…
Improved Neutron-Capture Element Abundances in Planetary Nebulae
N. C. Sterling, H. L. Dinerstein, S. Hwang +11
Spectroscopy of planetary nebulae (PNe) provides the means to investigate s-process enrichments of neutron(n)-capture elements that cannot be detected in asymptotic giant branch (A…
Effect of quantization of vibrations on the structural properties of crystals
I. Scivetti, N. I. Gidopoulos, J. Kohanoff
We study the structural effects produced by the quantization of vibrational degrees of freedom in periodic crystals at zero temperature. To this end we introduce a methodology base…
