Configuration interaction calculation for the isotope shift in Mg I
J. C. Berengut, V. A. Dzuba, V. V. Flambaum +1
We present an ab initio method of calculation of isotope shift in atoms with a few valence electrons, based on the configuration-interaction calculation of energy. The main motivat…
Understanding B-type Supergiants in the Low Metallicity Environment of the SMC
C. Trundle, D. J. Lennon, J. Puls +1
Spectroscopic analyses of 7 SMC B-type supergiants and 1 giant have been undertaken using high resolution optical data obtained on the VLT with UVES. FASTWIND, a non-LTE, spherical…
Third homology of general linear groups
Behrooz Mirzaii
The third homology group of GL_n(R) is studied, where R is a `ring with many units' with center Z(R). The main theorem states that if K_1(Z(R))_Q \simeq K_1(R)_Q, (e.g. R a commuta…
The H alpha Galaxy Survey I. The galaxy sample, H alpha narrow-band observations and star formation parameters for 334 galaxies
P. A. James, N. S. Shane, J. E. Beckman +12
We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe. The sample consist…
Polarization control of optical transmission of a periodic array of elliptical holes in a metal film
Jill Elliott, Igor I. Smolyaninov, Nikolay I. Zheludev +1
Spectral dependencies of polarized optical transmission of a metal film with a periodic array of elliptical nanoholes have been studied. Such nanostructured metal films exhibit the…
AF-embeddings into C*-algebras of real rank zero
Francesc Perera, Mikael Rordam
It is proved that every separable -algebra of real rank zero contains an AF-sub--algebra such that the inclusion mapping induces an isomorphism of the ideal lattices of t…
Grain Size Distributions and Photo-Electric Heating in Ionized Regions
P. A. M. van Hoof, J. C. Weingartner, P. G. Martin +2
In this paper we present results obtained with the new grain code in Cloudy which underline the strong effect of photo-electric heating by grains in photo-ionized regions. We study…
The Post-Agb Star IRAS 16594-4656
Griet C. Van de Steene, Peter A. M. van Hoof
We present the basic properties of the multipolar post-AGB star IRAS 16594-4656, and discuss in particular its near infrared spectrum which shows shock excited H2 and [Fe II] emiss…
D-outcome measurement for a nonlocality test
W. Son, Jinhyoung Lee, M. S. Kim
For the purpose of the nonlocality test, we propose a general correlation observable of two parties by utilizing local -outcome measurements with SU() transformations and cla…
Vacuum diamagnetism of mesoscopic metallic samples
Igor I. Smolyaninov
Zero-point energy of surface plasmon modes of mesoscopic metal samples in an external magnetic field has been considered. The magnetic response of plasmon vacuum has shown to be di…
Superfluid toroidal currents in atomic condensates
Eileen Nugent, Dermot McPeake, J F McCann
The dynamics of toroidal condensates in the presence of condensate flow and dipole perturbation have been investigated. The Bogoliubov spectrum of condensate is calculated for an o…
Are current-induced forces conservative?
M. Di Ventra, Yu-Chang Chen, T. N. Todorov
The expression for the force on an ion in the presence of current can be derived from first principles without any assumption about its conservative character. However, energy func…
Introducing EMILI: Computer Aided Emission Line Identification
Brian Sharpee, Robert Williams, Jack A. Baldwin +1
The identification of spectral lines can be a tedious process requiring the interrogation of large spectroscopic databases, but it does lend itself to software algorithms that can…
Entanglement between two superconducting qubits via interaction with non-classical radiation
Mauro Paternostro, Giuseppe Falci, Myungshik Kim +1
We propose a scheme to physically interface superconducting nano-circuits and quantum optics. We address the transfer of quantum information between systems having different physic…
Gravitating Fermionic Lumps with a False Vacuum Core
Ramin G. Daghigh, Yutaka Hosotani
We investigate gravitating lumps with a false vacuum core surrounded by the true vacuum in a scalar field potential. Such configurations become possible in the Einstein gravity in…
Broken Time Reversal of Light Interaction with Planar Chiral Nanostructures
A. S. Schwanecke, A. Krasavin, D. M. Bagnall +3
We report unambiguous experimental evidence of broken time reversal symmetry for the interaction of light with an artificial non-magnetic material. Polarized colour images of plana…
Shock emission in the bipolar post-AGB star IRAS 16594-4656
G. C. Van de Steene, P. A. M. van Hoof
In this paper we study the near-infrared emission spectrum of IRAS 16594-4656, a bipolar post-AGB star with spectral type B7 and no observed ionization. Using optical and near-infr…
Magnetic light
Igor I. Smolyaninov, Jill Elliott, Anatoly V. Zayats
In this paper we report on the observation of novel and highly unusual magnetic state of light. It appears that in small holes light quanta behave as small magnets so that light pr…
Eclipse observations of high-frequency oscillations in active region coronal loops
A. C. Katsiyannis, D. R. Williams, R. T. J. McAteer +3
One of the mechanisms proposed for heating the corona above solar active regions is the damping of magnetohydrodynamic (MHD) waves. Continuing on previous work, we provide observat…
