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…
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…
Generating "squeezed" superpositions of coherent states using photon addition and subtraction
P. Marek, H. Jeong, M. S. Kim
We study how photon addition and subtraction can be used to generate squeezed superpositions of coherent states in free-traveling fields (SSCSs) with high fidelities and large ampl…
