  • Wilcox, Stuart; Botten, Lindsay; Mcphedran, Ross; Poulton, Christopher; De Sterke, C (American Physical Soc, 2005)
    We present an exact theory for modeling defect modes in two-dimensional photonic crystals having an infinite cladding. The method is based on three key concepts, namely, the use of fictitious sources to modify response ...
  • Kan, Dougal; Asatryan, Ara; Poulton, Christopher; Dossou, Kokou; Botten, Lindsay (Optical Society of America, 2011)
    We extend the fictitious source superposition method in order to model linear defects in photonic woodpiles, and we use the method to model a waveguide that is created by changing either the radius or refractive index of ...
  • Zhang, Nong; Kirpitchenko, Inessa (Academic Press, 2002)
    This paper presents the concept of a vibration control system in which motions of a continuous structure with piezoelectric sensors/actuators can be suppressed (or activated) through transforming mechanical energy to ...
  • Pearce G; Weiderhecker G; Poulton Christopher; Burger S; Russell P (Optical Society of America, 2007)
    We demonstrate by numerical simulation that the general features of the loss spectrum of photonic crystal fibres (PCF) with a kagome structure can be explained by simple models consisting of thin concentric hexagons or ...
  • De Sterke, C; Botten, Lindsay; Asatryan, Ara; White, Tom; Mcphedran, Ross (Optical Society of America, 2004)
    We consider the modes of coupled photonic crystal waveguides. We find that the fundamental modes ofthese structures can be either even or odd, in contrast with the behaviour in coupled conventional waveguides in which the ...
  • Andreasen, J; Asatryan, Ara; Botten, Lindsay; Byrne, M; Cao, H; Ge, L; Labonte, L; Sebbah, P; Stone, A; T??Reci, H; Vanneste, C (Optical Society of America, 2011)
    In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, directivity, and polarization. In random lasers, which ...
  • Dossou, Kokou; Poulton, Christopher; Botten, Lindsay; Mahmoodian, Sahand; Mcphedran, Ross; De Sterke, C (American Physical Society, 2009)
    We consider the modal fields and resonance frequencies of composite defects in two-dimensional photonic crystals (PCs). Using an asymptotic method based on Green's functions, we show that the coupling matrices for the ...
  • Ton-That, Cuong; Shard, Alex; Egger, S.; Dhanak, Vinod; Welland, Mark (American Physical Society, 2003)
    The photon-energy dependences of valence-band photoemission spectra have been investigated for monolayer, submonolayer, and multilayer C60 films on Ag(111). The intensity ratios of the highest and next-highest occupied ...
  • Ranjbartoreh, Ali Rezah; Wang, Guoxiu (Elsevier BV, 2010)
    This paper investigates the effects of length's variations on Young's modulus, compressive elastic modulus, tensile, compressive, and lateral stiffness, critical buckling strain, critical axial force and pressure of armchair ...
  • Dredge, Paula; Wuhrer, Ric; Phillips, Matt (Cambridge Univ Press, 2003)
    An oil painting by Claude Monet, Port-Goulphar, Belle-Ile 1887 (collection of the Art Gallery of New South Wales), was examined to determine both the identity of the pigments used by the artist in this painting and his ...
  • Gou, Xinglong; Wang, Guoxiu; Park, Jinsoo; Liu, Hao; Yang, Juan (Institute of Physics (UK), 2008)
    Monodisperse a-Fe2O3 porous nanospheres with uniform shape and size have been synthesized via a facile template-free route. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy ...
  • Frenkel, Robert; Kirkup, Les (Bureau Int Poids Mesures, 2005)
    We have used a Monte Carlo simulation for investigating the output of a digital instrument, of resolution half-width a, when its analogue input is a Gaussian signal. The digitizing process converts an actual mean to an ...
  • Barnard, Amanda; Feigl, Christopher; Russo, Salvy (R S C Publications, 2010)
    Zinc sulfide (ZnS) nanoparticles are of interest for their luminescent and catalytic properties which are being considered for the next generation of optical, electronic and photovoltaic devices. However, ZnS nanoparticles ...
  • Hannoyer, B.; Prince, A.; Jean, M.; Liu, R.; Wang, Guoxiu (Springer Netherlands, 2006)
    Crystalline LiFePO4 has been synthesized using solid-state, spray pyrolysis, and wet chemical methods. The crystal parameters were obtained from Rietveld?s refinement methods of the X-ray diffraction patterns. A detailed ...
  • Moran, Ken; Wuhrer, Ric; Phillips, Matt (Cambridge University Press, 2008)
    X-ray mapping with Silicon Drift detectors (SDD?s) and multi-EDS detector systems has become an invaluable analysis technique because the time to perform an x-ray map is reduced considerably. Live x-ray imaging can now ...
  • Chitambar, Eric; Duan, Runyao; Shi, Yuquan (Amer Physical Soc, 2010)
    We consider the problem of deciding if some multiparty entangled pure state can be converted, with a nonzero success probability, into a given bipartite pure state shared between two specified parties through local quantum ...
  • Wang, Guoming; Ying, Mingsheng (American Physical Soc, 2007)
    We find an interesting relationship between multipartite bound entangled states and the stabilizer formalism. We prove that, if a set of commuting operators from the generalized Pauli group on n qudits satisfy certain ...
  • Yu, Nengkun (Amer Physical Soc, 2013)
    It is known that the n-qubit W-type state is determined by its bipartite reduced density matrices. In this paper, we show that the multipartite W-type state is uniquely determined by its reduced density matrices among ...
  • Duan, Runyao; Feng, Yuan; Li, X; Ying, Mingsheng (American Physical Soc, 2005)
    We prove that any multiple-copy entanglement transformation [S. Bandyopadhyay, V. Roychowdhury, and U. Sen, Phys. Rev. A 65, 052315 (2002)] can be implemented by a suitable entanglement-assisted local transformation [D. ...
  • White, Tom; Kuhlmey, Boris; Mcphedran, Ross; Maystre, Daniel; Renversez, Gilles; De Sterke, C; Botten, Lindsay (Optical Society of America, 2002)
    We describe a multipole method for calculating the modes of microstructured optical fibers. The method uses a multipole expansion centered on each hole to enforce boundary conditions accurately and matches expansions with ...
