The environment of weak emission-line quasars
Marek Nikolajuk, Roland Walter
The nature of weak emission-line quasars (WLQs) is probed by comparing the Baldwin effect (BEff) in WLQs and normal quasars (QSOs). We selected 81 high-redshift (z>2.2) and 2 inter…
Upper limits on a stochastic gravitational-wave background using LIGO and Virgo interferometers at 600-1000 Hz
J. Abadie, B. P. Abbott, R. Abbott +782
A stochastic background of gravitational waves is expected to arise from a superposition of many incoherent sources of gravitational waves, of either cosmological or astrophysical…
Search for Gravitational Waves from Low Mass Compact Binary Coalescence in LIGO's Sixth Science Run and Virgo's Science Runs 2 and 3
the LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +796
We report on a search for gravitational waves from coalescing compact binaries using LIGO and Virgo observations between July 7, 2009 and October 20, 2010. We searched for signals…
All-sky Search for Periodic Gravitational Waves in the Full S5 LIGO Data
J. Abadie, B. P. Abbott, R. Abbott +794
We report on an all-sky search for periodic gravitational waves in the frequency band 50-800 Hz and with the frequency time derivative in the range of 0 through -6e-9 Hz/s. Such a…
Directional limits on persistent gravitational waves using LIGO S5 science data
J. Abadie, B. P. Abbott, R. Abbott +712
The gravitational-wave (GW) sky may include nearby pointlike sources as well as astrophysical and cosmological stochastic backgrounds. Since the relative strength and angular distr…
Implementation and testing of the first prompt search for gravitational wave transients with electromagnetic counterparts
The LIGO Scientific Collaboration, Virgo Collaboration, J. Abadie +815
Aims. A transient astrophysical event observed in both gravitational wave (GW) and electromagnetic (EM) channels would yield rich scientific rewards. A first program initiating EM…
Coherent Backscattering of Ultracold Matter Waves: Momentum Space Signatures
Nicolas Cherroret, Tomasz Karpiuk, Cord A. Müller +2
Using analytical and numerical methods, it is shown that the momentum distribution of a matter wave packet launched in a random potential exhibits a pronounced coherent backscatter…
Mössbauer studies of powdered single crystals of FeTe0.5Se0.5
K. Szymański, W. Olszewski, L. Dobrzyński +5
The Mössbauer measurements performed on powdered single crystals of FeTe0.5Se0.5 (Tc ~ 14.7 K) reveal minor content of two impurity phases, identified as Fe3O4 and Fe7Se8, among th…
Large Formal Wikis: Issues and Solutions
Jesse Alama, Kasper Brink, Lionel Mamane +1
We present several steps towards large formal mathematical wikis. The Coq proof assistant together with the CoRN repository are added to the pool of systems handled by the general…
Integrable relativistic systems given by Hamiltonians with momentum-spin-orbit coupling
Alina Dobrogowska, Anatol Odzijewicz
In the paper we investigate the evolution of the relativistic particle (massive and massless) with spin defined by Hamiltonian containing the terms with momentum-spin-orbit couplin…
Hierarchy of integrable Hamiltonians describing of nonlinear n-wave interaction
Anatol Odzijewicz, Tomasz Goliński
In the paper we construct an hierarchy of integrable Hamiltonian systems which describe the variation of n-wave envelopes in nonlinear dielectric medium. The exact solutions for so…
The flare model for X-ray variability of NGC 4258
T. Trzesniewski, B. Czerny, V. Karas +4
We study the variability mechanism of active galactic nuclei (AGN) within the framework of the flare model. To this end we examine the case of Seyfert/LINER galaxy NGC 4258, which…
Classical mechanics of many particles defined on canonically deformed nonrelativistic space-time
Marcin Daszkiewicz, Cezary J. Walczyk
We provide the classical mechanics of many particles moving in canonically twist-deformed space-time. In particular, we consider two examples of such noncommutative systems - the s…
Beating the spin-down limit on gravitational wave emission from the Vela pulsar
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +747
We present direct upper limits on continuous gravitational wave emission from the Vela pulsar using data from the Virgo detector's second science run. These upper limits have been…
Constraints on the black hole spin in the quasar SDSS J094533.99+100950.1
Bozena Czerny, Krzysztof Hryniewicz, Marek Nikolajuk +1
The spin of the black hole is an important parameter which may be responsible for the properties of the inflow and outflow of the material surrounding a black hole. Broad band IR/o…
Two component Bose-Hubbard model with higher angular momentum states
J. Pietraszewicz, T. Sowinski, M. Brewczyk +3
We study a Bose-Hubbard Hamiltonian of ultracold two component gas of spinor Chromium atoms. Dipolar interactions of magnetic moments while tuned resonantly by ultralow magnetic fi…
Search for gravitational waves from binary black hole inspiral, merger and ringdown
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +721
We present the first modeled search for gravitational waves using the complete binary black hole gravitational waveform from inspiral through the merger and ringdown for binaries w…
Tunable dipolar resonances and Einstein-de Haas effect in a Rb-87 atoms condensate
Tomasz Swislocki, Tomasz Sowinski, Joanna Pietraszewicz +4
We study a spinor condensate of Rb-87 atoms in F = 1 hyperfine state confined in an optical dipole trap. Putting initially all atoms in mF = 1 component we observe a significant tr…
Transitivity of an entangled choice
Marcin Makowski, Edward W. Piotrowski
We describe a quantum model of simple choice game (constructed upon entangled state of two qubits), which involves the fundamental problem of transitive - intransitive preferences.…
Decisions in elections --- transitive or intransitive quantum preferences
Marcin Makowski, Edward W. Piotrowski
Our preferences depend on the circumstances in which we reveal them. We will introduce a dependency which allows us to illustrate the relation between the possibility of winning of…
