Quark distributions in nuclear matter and the EMC effect
H. Mineo, W. Bentz, N. Ishii +2
Quark light cone momentum distributions in nuclear matter and the structure function of a bound nucleon are investigated in the framework of the Nambu-Jona-Lasinio model. This fram…
Nonperturbative renormalisation of composite operators with overlap quarks
J. B. Zhang, D. B. Leinweber, K. F. Liu +1
We compute non-perturbatively the renormalisation constants of composite operators on a lattice with lattice spacing = 0.093 fm for the overlap fermion action…
Constructions with bundle gerbes
Stuart Johnson
This thesis develops the theory of bundle gerbes and examines a number of useful constructions in this theory. These allow us to gain a greater insight into the structure of bundle…
A Method to Unambiguously Determine the Parity of the Theta+ Pentaquark
A. W. Thomas, K. Hicks, A. Hosaka
With the recent discovery of the pentaquark, the question of its parity is paramount since this will constrain the correct description of its internal structure. We show…
T-duality for principal torus bundles
Peter Bouwknegt, Keith Hannabuss, Varghese Mathai
In this paper we study T-duality for principal torus bundles with H-flux. We identify a subset of fluxes which are T-dualizable, and compute both the dual torus bundle as well as t…
A Note on the Equality of Algebraic and Geometric D-Brane Charges in WZW Models
Peter Bouwknegt, David Ridout
The algebraic definition of charges for symmetry-preserving D-branes in Wess-Zumino-Witten models is shown to coincide with the geometric definition, for all simple Lie groups. The…
On the Topology and Flux of T-Dual Manifolds
Peter Bouwknegt, Jarah Evslin, Varghese Mathai
We present a general formula for the topology and H-flux of the T-dual of a type two compactification. Our results apply to T-dualities with respect to any free circle action. In p…
Some Relations between Twisted K-theory and E8 Gauge Theory
Varghese Mathai, Hisham Sati
Recently, Diaconescu, Moore and Witten provided a nontrivial link between K-theory and M-theory, by deriving the partition function of the Ramond-Ramond fields of Type IIA string t…
Topological Charge Evolution in the Markov-Chain of QCD
Derek B. Leinweber, Anthony G. Williams, Jian-bo Zhang +1
The topological charge is studied on lattices of large physical volume and fine lattice spacing. We illustrate how a parity transformation on the SU(3) link-variables of lattice ga…
Chiral extrapolation and physical insights
R. D. Young, D. B. Leinweber, A. W. Thomas
It has recently been established that finite-range regularisation in chiral effective field theory enables the accurate extrapolation of modern lattice QCD results to the chiral re…
Ultra High Energy Cosmic Rays
R. J. Protheroe, R. W. Clay
Cosmic rays with energies above eV are currently of considerable interest in astrophysics and are to be further studied in a number of projects which are either currently…
Extended Theory of Finite Fermi Systems (Collective Vibrations in Closed Shell Nuclei)
S. Kamerdzhiev, J. Speth, G. Tertychny
We review an extension of Migdal's Theory of Finite Fermi Systems which has been developed and applied to collective vibrations in closed shell nuclei in the past ten years. This m…
Neutrino Physics Without Oscillations
A. W. Thomas
There is a tremendous potential for neutrinos to yield valuable new information about strongly interacting systems. Here we provide a taste of this potential, beginning with the ex…
Quantum random walks with history dependence
Adrian P. Flitney, Derek Abbott, Neil F. Johnson
We introduce a multi-coin discrete quantum random walk where the amplitude for a coin flip depends upon previous tosses. Although the corresponding classical random walk is unbiase…
Arithmetic properties of eigenvalues of generalized Harper operators on graphs
J. Dodziuk, V. Mathai, S. Yates
Let $\Qbar$ denote the field of complex algebraic numbers. A discrete group is said to have the -multiplier algebraic eigenvalue property, if for every matrix with entri…
Realisation of chiral symmetry in the domain model of QCD
A. C. Kalloniatis, S. N. Nedelko
The domain model for the QCD vacuum has previously been developed and shown to exhibit confinement of quarks and strong correlation of the local chirality of quark modes and dualit…
Stochastic Cellular Automata Model for Stock Market Dynamics
M. Bartolozzi, A. W. Thomas
In the present work we introduce a stochastic cellular automata model in order to simulate the dynamics of the stock market. A direct percolation method is used to create a hierarc…
Axial U(1) and spontaneous chiral symmetry breaking within a confining model of the QCD vacuum
A. C. Kalloniatis, S. N. Nedelko
A model for the QCD vacuum based on domain-like background gluon fields has previously been developed and demonstrated to exhibit confinement of quarks and strong correlation of th…
Type I D-branes in an H-flux and twisted KO-theory
V. Mathai, M. K. Murray, D. Stevenson
Witten has argued that charges of Type I D-branes in the presence of an H-flux, take values in twisted KO-theory. We begin with the study of real bundle gerbes and their holonomy.…
Chiral Structure in Baryon Magnetic Moments
R. D. Young, D. B. Leinweber, A. W. Thomas
We highlight recent advances in finite-range regularised chiral effective field theory. Application to baryon magnetic moments show an unambiguous signal of quenched chiral physics…
Electromagnetic Form Factors with FLIC Fermions
J. M. Zanotti, D. B. Leinweber, A. G. Williams +1
The Fat-Link Irrelevant Clover (FLIC) fermion action provides a new form of nonperturbative O(a) improvement and allows efficient access to the light quark-mass regime. FLIC fermio…
Dynamical FLIC Fermions
W. Kamleh, D. B. Leinweber, A. G. WIlliams
The use of APE smearing or other blocking techniques in fermion actions can provide many advantages. There are many variants of these fat link actions in lattice QCD currently, suc…
An Algorithm for Obtaining Reliable Priors for Constrained-Curve Fits
Terrence Draper, Shao-Jing Dong, Ivan Horvath +3
We introduce the ``Sequential Empirical Bayes Method'', an adaptive constrained-curve fitting procedure for extracting reliable priors. These are then used in standard augmented-ch…
Scaling Behavior of the Landau Gauge Overlap Quark Propagator
J. B. Zhang, F. D. R. Bonnet, P. O. Bowman +2
The properties of the momentum space quark propagator in Landau gauge are examined for the overlap quark action in quenched lattice QCD. Numerical calculations are done on three la…
