More elementary operators that are spectrally bounded
Nadia Boudi, Martin Mathieu
We discuss some necessary and some sufficient conditions for an elementary operator on a Banach algebra to be spectrally bounded. In the case of…
A Search for Photometric Variability Towards M71 with the Near-Infrared Transiting ExoplanetS Telescope
J. McCormac, I. Skillen, D. Pollacco +5
We present the results of a high-cadence photometric survey of an field centred on the globular cluster M71, with the Near-Infrared Transiting ExoplanetS Telescope.…
Electron recombination, photoionization and scattering via many-electron compound resonances
V. A. Dzuba, V. V. Flambaum, G. F. Gribakin +2
Highly excited eigenstates of atoms and ions with open f shell are chaotic superpositions of thousands, or even millions of Hartree-Fock determinant states. The interaction between…
Experimental linear-optics simulation of the ground state of an interacting quantum spin-ring
Adeline Orieux, Joelle Boutari, Marco Barbieri +2
Critical phenomena involve a structural change in the correlations of its constituents. These features can be employed in quantum simulators to assess when a criticality occurred i…
Reconfigurable long-range phonon dynamics in optomechanical arrays
André Xuereb, Claudiu Genes, Guido Pupillo +2
We investigate periodic optomechanical arrays as reconfigurable platforms for engineering the coupling between multiple mechanical and electromagnetic modes and for exploring many-…
The Generalized Langevin Equation: An efficient approach to non-equilibrium molecular dynamics of open systems
L. Stella, C. D. Lorenz, L. Kantorovich
The Generalized Langevin Equation (GLE) has been recently suggested to simulate the time evolution of classical solid and molecular systems when considering general non-equilibrium…
Characterizing and Extending Answer Set Semantics using Possibility Theory
Kim Bauters, Steven Schockaert, Martine De Cock +1
Answer Set Programming (ASP) is a popular framework for modeling combinatorial problems. However, ASP cannot easily be used for reasoning about uncertain information. Possibilistic…
Ultracold hydrogen and deuterium production via Doppler-cooled Feshbach molecules
Ian Lane
A counterintuitive scheme to produce ultracold hydrogen via fragmentation of laser cooled diatomic hydrides is presented where the final atomic H temperature is inversely proportio…
Quantum chromatic numbers via operator systems
Vern I. Paulsen, Ivan G. Todorov
We define several new types of quantum chromatic numbers of a graph and characterise them in terms of operator system tensor products. We establish inequalities between these chrom…
Energy levels, radiative rates and electron impact excitation rates for transitions in Al X
K. M. Aggarwal, F. P. Keenan
Energy levels, radiative rates and lifetimes are calculated among the lowest 98 levels of the n <= 4 configurations of Be-like Al X. The GRASP (General-purpose Relativistic Atomic…
Estimating Stellar Radial Velocity Variability from Kepler and GALEX: Implications for the Radial Velocity Confirmation of Exoplanets
H. M. Cegla, K. G. Stassun, C. A. Watson +2
We cross-match the GALEX and Kepler surveys to create a unique dataset with both ultraviolet (UV) measurements and highly precise photometric variability measurements in the visibl…
SN 2009N: Linking normal and subluminous type II-P SNe
K. Takáts, M. L. Pumo, N. Elias-Rosa +31
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a type II-P supernova with spectra resembling those of subluminou…
Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Adaptive Measurement-Based Policy-Driven QoS Management with Fuzzy-Rule-based Resource Allocation
Suleiman Y. Yerima, Gerard P. Parr, Sally I. McClean +1
Fixed and wireless networks are increasingly converging towards common connectivity with IP-based core networks. Providing effective end-to-end resource and QoS management in such…
Implementation and Evaluation of Measurement-Based Admission Control Schemes Within a Converged Networks QoS Management Framework
Suleiman Y. Yerima
Policy-based network management (PBNM) paradigms provide an effective tool for end-to-end resource management in converged next generation networks by enabling unified, adaptive an…
Variability of the High Velocity Outflow in the Quasar PDS 456
J. N. Reeves, V. Braito, J. Gofford +9
We present a comparison of two Suzaku X-ray observations of the nearby (z=0.184), luminous ( erg s) type I quasar, PDS456. A new 125ks Suzaku observati…
Energy levels and radiative rates for transitions in Ti VII
KM Aggarwal, FP Keenan
We report calculations of energy levels, radiative rates, oscillator strengths and line strengths for transitions among the lowest 231 levels of Ti VII. The general-purpose relativ…
