The structure of shock waves as a test of Brenner's modifications to the Navier-Stokes equations
Christopher J. Greenshields, Jason M. Reese
Brenner has recently proposed modifications to the Navier-Stokes equations that are based on theoretical arguments but supported only by experiments having a fairly limited range.…
dHybrid: a massively parallel code for hybrid simulations of space plasmas
L. Gargaté, R. Bingham, R. A. Fonseca +1
A massively parallel simulation code, called \textit{dHybrid}, has been developed to perform global scale studies of space plasma interactions. This code is based on an explicit hy…
Quantum Formulation of Fractional Orbital Angular Momentum
J. B. Goette, S. Franke-Arnold, R. Zambrini +1
The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to non-integer values of the orbital angular momentum. This…
Statistical regimes of random laser fluctuations
Stefano Lepri, Stefano Cavalieri, Gian-Luca Oppo +1
Statistical fluctuations of the light emitted from amplifying random media are studied theoretically and numerically. The characteristic scales of the diffusive motion of light lea…
Experimental Realization of Maximum Confidence State Discrimination for the Extraction of Quantum Information
Peter J. Mosley, Sarah Croke, Ian A. Walmsley +1
We present the first experimental demonstration of the maximum confidence measurement strategy for quantum state discrimination. Applying this strategy to an arbitrary set of state…
Effects of CO2 on H2O band profiles and band strengths in mixed H2O:CO2 ices
Karin I. Oberg, Helen J. Fraser, A. C. Adwin Boogert +4
H2O is the most abundant component of astrophysical ices. In most lines of sight it is not possible to fit both the H2O 3 um stretching, the 6 um bending and the 13 um libration ba…
Eigen modes for the problem of anomalous light transmission through subwavelength holes
B. Sturman, E. Podivilov, M. Gorkunov
We show that the wide-spread concept of optical eigen modes in lossless waveguide structures, which assumes the separation on propagating and evanescent modes, fails in the case of…
Maximum observable correlation for a bipartite quantum system
Michael J. W. Hall, Erika Andersson, Thomas Brougham
The maximum observable correlation between the two components of a bipartite quantum system is a property of the joint density operator, and is achieved by making particular measur…
Dielectronic recombination of Fe 3p^q ions: a key ingredient for describing X-ray absorption in active galactic nuclei
N. R. Badnell
We have carried-out multi-configuration Breit-Pauli AUTOSTRUCTURE calculations for the dielectronic recombination (DR) of Fe^{8+} - Fe^{12+} ions. We obtain total DR rate coefficie…
Statistical properties of the continuum Salerno model
M. Marklund, P. K. Shukla, R. Bingham +1
The statistical properties of the Salerno model is investigated. In particular, a comparison between the coherent and partially coherent wave modes is made for the case of a random…
Operational approach to the Uhlmann holonomy
Johan Aberg, David Kult, Erik Sjöqvist +1
We suggest a physical interpretation of the Uhlmann amplitude of a density operator. Given this interpretation we propose an operational approach to obtain the Uhlmann condition fo…
Retrodictive fidelities for pure state postselectors
John Jeffers
Two measures of fidelity are proposed for postselecting devices, the retrodictive conditional probability that the state in the measurement arm is the one indicated by the detector…
Stylized facts from a threshold-based heterogeneous agent model
R. Cross, M. Grinfeld, H. Lamba +1
A class of heterogeneous agent models is investigated where investors switch trading position whenever their motivation to do so exceeds some critical threshold. These motivations…
Nonlinear propagation of broadband intense electromagnetic waves in an electron-positron plasma
M. Marklund, B. Eliasson, P. K. Shukla
A kinetic equation describing the nonlinear evolution of intense electromagnetic pulses in electron-positron (e-p) plasmas is presented. The modulational instability is analyzed fo…
Dielectronic recombination of Fe^{13+}: benchmarking the M-shell
N. R. Badnell
We have carried-out a series of multi-configuration Breit-Pauli AUTOSTRUCTURE calculations for the dielectronic recombination of Fe^{13+}. We present a detailed comparison of the r…
Scalable Error Correction in Distributed Ion Trap Computers
Daniel K. L. Oi, Simon J. Devitt, Lloyd C. L. Hollenberg
A major challenge for quantum computation in ion trap systems is scalable integration of error correction and fault tolerance. We analyze a distributed architecture with rapid high…
Fourier relationship between angular position and optical orbital angular momentum
Eric Yao, Sonja Franke-Arnold, Johannes Courtial +2
We demonstrate the Fourier relationship between angular position and angular momentum for a light mode. In particular we measure the distribution of orbital angular momentum states…
Direct measurement of penetration length in ultra-thin and/or mesoscopic superconducting structures
L. Hao, J. C. Macfarlane, J. C. Gallop +1
We describe a method for direct measurement of the magnetic penetration length in thin (10 - 100 nm) superconducting structures having overall dimensions in the range 1 to 100 micr…
Coherent searches for periodic gravitational waves from unknown isolated sources and Scorpius X-1: results from the second LIGO science run
The LIGO Scientific Collaboration
We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. The first search is targeted at isolated, pr…
Phase-dependent light propagation in atomic vapors
S. Kajari-Schroeder, G. Morigi, S. Franke-Arnold +1
Light propagation in an atomic medium whose coupled electronic levels form a diamond-configuration exhibits a critical dependence on the input conditions. In particular, the relati…
