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…
PIC simulation of a strong double layer in a nonrelativistic plasma flow: Electron acceleration to ultrarelativistic speeds
M E Dieckmann, A Bret
Two charge- and current neutral plasma beams are modelled with a one-dimensional PIC simulation. The beams are uniform and unbounded. The relative speed between both beams is 0.4c.…
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…
Qubit residence time measurements with a Bose-Einstein condensate
D. Sokolovski
We show that an electrostatic qubit located near a Bose-Einstein condensate trapped in a symmetric double-well potential can be used to measure the duration the qubit has spent in…
A dissipative scheme to approach the boundary of two-qubit entangled mixed states
S. Campbell, M. Paternostro
We discuss the generation of states close to the boundary-family of maximally entangled mixed states as defined by the use of concurrence and linear entropy. The coupling of two qu…
Hamiltonian tomography in an access-limited setting without state initialization
C. Di Franco, M. Paternostro, M. S. Kim
We propose a scheme for the determination of the coupling parameters in a chain of interacting spins. This requires only time-resolved measurements over a single particle, simple d…
Rising time of entanglement between scattering spins
F. Ciccarello, M. Paternostro, G. M. Palma +1
We investigate the time evolution of entanglement in a process where a mobile particle is scattered by static spins. We show that entanglement increases monotonically during a tran…
Ergodic Capacity Analysis of Amplify-and-Forward MIMO Dual-Hop Systems
Shi Jin, Matthew R. McKay, Caijun Zhong +1
This paper presents an analytical characterization of the ergodic capacity of amplify-and-forward (AF) MIMO dual-hop relay channels, assuming that the channel state information is…
Effects of accretion flow on the chemical structure in the inner regions of protoplanetary disks
H. Nomura, Y. Aikawa, Y. Nakagawa +1
We have studied the dependence of the profiles of molecular abundances and line emission on the accretion flow in the hot ($\ga 100$K) inner region of protoplanetary disks. The gas…
Single-photon excitation of surface plasmon polaritons
M. S. Tame, C. Lee, J. Lee +4
We provide the quantum mechanical description of the excitation of surface plasmon polaritons on metal surfaces by single-photons. An attenuated-reflection setup is described for t…
The Maximal C*-Algebra of Quotients as an Operator Bimodule
Pere Ara, Martin Mathieu, Eduard Ortega
We establish a description of the maximal C*-algebra of quotients of a unital C*-algebra as a direct limit of spaces of completely bounded bimodule homomorphisms from certain o…
A combined R-matrix eigenstate basis set and finite-differences propagation method for the time-dependent Schr\"{od}dinger equation: the one-electron case
L. A. A. Nikolopoulos, J. S. Parker, K. T. Taylor
In this work we present the theoretical framework for the solution of the time-dependent Schrödinger equation (TDSE) of atomic and molecular systems under strong electromagnetic fi…
Do all Flares have White Light Emission?
D. B. Jess, M. Mathioudakis, P. J. Crockett +1
High-cadence, multiwavelength optical observations of a solar active region (NOAA 10969), obtained with the Swedish Solar Telescope, are presented. Difference imaging of white ligh…
Physical Properties of Main-Belt Comet P/2005 U1 (Read)
Henry H. Hsieh, David Jewitt, Masateru Ishiguro
The main-belt comets occupy dynamically asteroidal orbits in the main asteroid belt. Here we present physical observations of the second-known member of this population, P/2005 U1…
VLT detection of a red supergiant progenitor of the type IIP supernova 2008bk
S. Mattila, S. J. Smartt, J. J. Eldridge +3
We report the identification of a source coincident with the position of the nearby type II-P supernova (SN) 2008bk in high quality optical and near-infrared pre-explosion images f…
SN 2006gy: was it really extra-ordinary?
I. Agnoletto, S. Benetti, E. Cappellaro +12
We present an optical photometric and spectroscopic study of the very luminous type IIn SN 2006gy for a time period spanning more than one year. In photometry, a broad, bright (M_R…
Positive phase space transformation incompatible with classical physics
Wonmin Son, Johannes Kofler, M. S. Kim +2
Bell conjectured that a positive Wigner function does not allow violation of the inequalities imposed by local hidden variable theories. A requirement for this conjecture is "when…

I. A. Steele, S. D. Bates, N. Gibson +5
By the precise timing of the low amplitude (0.005 - 0.02 magnitude) transits of exoplanets around their parent star it should be possible to infer the presence of other planetary b…
