  • Coupled ππ, KK̅ scattering in P-wave and the ρ resonance from lattice QCD 

    Wilson, David John; Briceño, Raúl A; Dudek, Jozef J; Edwards, Robert G; Thomas, Christopher Edward (APSPhysical Review D, 2015-11-02)
    We determine elastic and coupled-channel amplitudes for isospin-1 meson-meson scattering in P-wave, by calculating correlation functions using lattice QCD with light quark masses such that m_π = 236 MeV in a cubic volume ...

  • Coupled-channel $\textit{Dπ}$, $\textit{Dη}$ and $\textit{D$_{s}$$\bar K$}$ scattering from lattice QCD 

    Moir, Graham; Peardon, Michael; Ryan, Sinéad M; Thomas, Christopher Edward; Wilson, David John; on, behalf of the Hadron Spectrum collaboration (SpringerJournal of High Energy Physics, 2016-10-04)
    We present the first lattice QCD study of coupled-channel $\textit{Dπ}$, $\textit{Dη}$ and $\textit{D$_{s}$$\bar K$}$ scattering in isospin-1/2 in three partial waves. Using distillation, we compute matrices of correlation ...

  • Credit derivatives and sovereign debt 

    Goderis, Benedikt; Wagner, Wolf (CFAP, Cambridge Judge Business School, University of Cambridge, 2005-10)
    We study the introduction of credit protection on sovereign debt. We find that such protection reduces debtor moral hazard by allowing a bonghokder to improve his position in negotiations with the sovereign. Moreover, ...

  • Credit derivatives, the liquidity of bank assets and banking stability 

    Wagner, Wolf (CFAP, Cambridge Judge Business School, University of Cambridge, 2005)
    The emerging markets for credit derivatives have improved the liquidity of bank assets by providing banks with various new possibilities for selling and hedging their risks. This paper examines the consequences for banking ...

  • Credit risk transfer and financial sector performance 

    Wagner, Wolf; Marsh, Ian (CFAP, Cambridge Judge Business School, University of Cambridge, 2004)
    In this paper we study the impact of credit risk transfer (CRT) on the stability and the efficiency of a financial system in a model with endogenous intermediation and production. Our analysis suggests that with respect ...

  • Critical behaviour in charging of electric vehicles 

    Carvalho, Rui; Buzna, Lubos; Gibbens, Richard John; Kelly, Francis Patrick (IOP PublishingNew Journal of Physics, 2015-09-02)
    The increasing penetration of electric vehicles over the coming decades, taken together with the high cost to upgrade local distribution networks and consumer demand for home charging, suggest that managing congestion on ...

  • Critical Exponents on Fortuin-Kasteleyn Weighted Planar Maps 

    Berestycki, Nathanael Edouard; Laslier, Benoit; Ray, Gourab (SpringerCOMMUNICATIONS IN MATHEMATICAL PHYSICS, 2017-10-01)
    In this paper we consider random planar maps weighted by the self-dual Fortuin--Kasteleyn model with parameter $q \in (0,4)$. Using a bijection due to Sheffield and a connection to planar Brownian motion in a cone we obtain ...

  • Critical surface of the 1-2 model 

    Grimmett, Geoffrey Richard; Li, Z
    The 1-2 model on the hexagonal lattice is a model of statistical mechanics in which each vertex is constrained to have degree either 1 or 2. There are three edge directions, and three corresponding parameters a, b, c. It ...

  • Critical Surface of the Hexagonal Polygon Model 

    Grimmett, Geoffrey Richard; Li, Z (SpringerJournal of Statistical Physics, 2016-05-01)
    The hexagonal polygon model arises in a natural way via a transformation of the 1-2 model on the hexagonal lattice, and it is related to the high temperature expansion of the Ising model. There are three types of edge, and ...

  • Cross-sector policy research: insights from the UK energy and transport sectors 

    Peake, Stephen Robert (University of CambridgeDepartment of Engineering, 1993-10-26)
    Following established traditions in anthropology and sociology, where cross-border research helps to identify important themes which benefit from comparative study, this dissertation introduces cross-sector policy research ...

  • Crystallization and melting in geological fluid mechanics 

    Jarvis, Richard Allan (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 1991-07-12)

  • Cubulating hyperbolic free-by-cyclic groups: the irreducible case 

    Hagen, Mark Fearghus; Wise, Daniel T (Duke University PressDuke Mathematical Journal, 2016)
    Let V be a fi nite graph and let ∅ : V → V be an irreducible train track map whose mapping torus has word-hyperbolic fundamental group G. Then G acts freely and cocompactly on a CAT(0) cube complex. Hence, if F is a ...

  • Cyclic mixmaster universes 

    Barrow, John David; Ganguly, C (American Physical SocietyPhysical Review D, 2017-04-19)
    We investigate the behavior of bouncing Bianchi type IX “mixmaster” universes in general relativity. This generalizes all previous studies of the cyclic behavior of closed spatially homogeneous universes with and without ...

  • D-modules on rigid analytic spaces I 

    Ardakov, Konstantin; Wadsley, Simon James (De GruyterJournal für die reine und angewandte Mathematik, 2016)
    We introduce a sheaf of infinite order differential operators D on smooth rigid analytic spaces that is a rigid analytic quantisation of the cotangent bundle. We show that the sections of this sheaf over sufficiently small ...

  • D-modules on rigid analytic spaces II: Kashiwara’s equivalence 

    Ardakov, K; Wadsley, Simon James (American Mathematical SocietyJournal of Algebraic Geometry, 2018-01-01)
    Let X be a smooth rigid analytic space. We prove that the category of co-admissible D-cap-modules on a smooth rigid analytic space supported on a closed smooth subvariety is naturally equivalent to the category of co-admissible ...

  • Data analysis issues for allele-specific expression using Illumina's GoldenGate assay 

    Ritchie, Matthew E; Forrest, Matthew S; Dimas, Antigone S; Daelemans, Caroline; Dermitzakis, Emmanouil T; Deloukas, Panagiotis; Tavare, Simon (2010-05-26)
    Abstract Background High-throughput measurement of allele-specific expression (ASE) is a relatively new and exciting application area for array-based technologies. In this paper, we explore several data sets which make use ...

  • Data processing for the sandwiched Rényi divergence: a condition for equality 

    Leditzky, Felix; Rouzé, Cambyse; Datta, Nilanjana (SpringerLetters in Mathematical Physics, 2016)
    The $\alpha$-sandwiched Rényi divergence satisfies the data processing inequality, i.e. monotonicity under quantum operations, for $\alpha$ $\geq$ 1/2. In this article, we derive a necessary and sufficient algebraic condition ...

  • Decay of the Cosmic Vacuum Energy 

    Clifton, Timothy; Barrow, John D. (SpringerFestschrift, 2016)
    In his 2005 review, $\textit{Gravity and the Thermodynamics of Horizons}$, Paddy suggested that a vacuum in thermal equilibrium with a bath of radiation should have a gradually diminishing energy. We work through the ...

  • Decentralised network prediction and reconstruction algorithms 

    Yuan, Ye (University of CambridgeDepartment of Engineering, 2012-07-03)
    This study concerns the decentralised prediction and reconstruction problems in a network. First of all, we propose a decentralised prediction algorithm in the framework of network consensus problem. It allows any ...

  • Deep ocean clay crusts: behaviour and biological origin 

    Kuo, Matthew Yih-Han (University of CambridgeDepartment of Engineering, 2011-03-15)
    In water depths of 500m to greater than 2,000m, off the West coast of Africa, sediments comprise very soft clays with extremely high water contents and plasticity. In situ CPT and T-bar testing in these areas have identified ...
