The Montreal Blue Galaxy Survey III. Third list of UV-bright candidates
Roger Coziol, Serge Demers, Rémi Barnéoud +1
We present and discuss the latest addition of the Montreal Blue Galaxy (MBG) survey. Inspection of 59 Curtis Schmidt plates resulted in the identification of 135 new UV-bright gala…
A Superheated Droplet Detector for Dark Matter Search
L. A. Hamel, L. Lessard, L. Rainville +2
We discuss the operation principle of a detector based on superheated droplets of Freon-12 and its feasibility for the search of weakly interacting cold dark matter particles. In p…
Solutions of (2+1)-dimensional spin systems
Z. Thomova, P. Winternitz, W. J. Zakrzewski
We use the methods of group theory to reduce the equations of motion of two spin systems in (2+1) dimensions to sets of coupled ordinary differential equations. We present solution…
On The Power of Exact Quantum Polynomial Time
Gilles Brassard, Peter Hoyer
We investigate the power of quantum computers when they are required to return an answer that is guaranteed correct after a time that is upper-bounded by a polynomial in the worst…
CP Violation with Heavy Hadrons
David London
I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay , (ii) Charm: indirect CP violati…
Topology of amorphous tetrahedral semiconductors on intermediate lengthscales
Normand Mousseau, Laurent J. Lewis
Using the recently-proposed ``activation-relaxation technique'' for optimizing complex structures, we develop a structural model appropriate to a-GaAs which is almost free of odd-m…
Anyonic Realization of the Quantum Affine Lie Superalgebra U_q(A(M,N)^{(1)})
L. Frappat, A. Sciarrino, S. Sciuto +1
We give a realization of the quantum affine Lie superalgebras U_q(A(M,N))^(1) in terms of anyons defined on a one or two-dimensional lattice, the deformation parameter q being rela…
Confluent hypergeometric orthogonal polynomials related to the rational quantum Calogero system with harmonic confinement
Jan F. van Diejen
Two families (type and type ) of confluent hypergeometric polynomials in several variables are studied. We describe the orthogonality properties, differential equations, and…
Radiative Muon Capture on Hydrogen and the Induced Pseudoscalar Coupling
G. Jonkmans, S. Ahmad, D. S. Armstrong +24
The first measurement of the elementary process is reported. A photon pair spectrometer was used to measure the partial branching ratio ($2.10 \pm 0.22)…
NRQCD matrix elements in polarization of J-Psi produced from b-decay
Sean Fleming, Oscar F. Hernandez, Ivan Maksymyk +1
We present the non-relativistic QCD (NRQCD) prediction for the polarization of the J-Psi produced in b to J-Psi + X, as well as the helicity-summed production rate. We propose that…
Event-based relaxation of continuous disordered systems
G. T. Barkema, Normand Mousseau
A computational approach is presented to obtain energy-minimized structures in glassy materials. This approach, the activation-relaxation technique (ART), achieves its efficiency b…
Rodrigues formulas for the Macdonald polynomials
Luc Lapointe, Luc Vinet
We present formulas of Rodrigues type giving the Macdonald polynomials for arbitrary partitions through the repeated application of creation operators on the constant 1. Three expr…
Creation operators for the Macdonald and Jack polynomials
Luc Lapointe, Luc Vinet
Formulas of Rodrigues-type for the Macdonald polynomials are presented. They involve creation operators, certain properties of which are proved and other conjectured. The limiting…
Global morphology and physical relations between the stars, gas and dust in the disc and arms of M100
J. H. Knapen, J. E. Beckman
We study star formation processes in the disc of the weakly barred grand design spiral galaxy M100 (NGC 4321) from a variety of images tracing recent massive star formation, old an…
The Potential of Asteroseismology for Hot, Subdwarf B Stars: A New Class of Pulsating Stars?
Stephane Charpinet, Gilles Fontaine, Pierre Brassard +1
We present key sample results of a systematic survey of the pulsation properties of models of hot B subdwarfs. We use equilibrium structures taken from detailed evolutionary sequen…
The masses of the millisecond pulsar J1012+5307 and its white-dwarf companion
M. H. van Kerkwijk, P. Bergeron, S. R. Kulkarni
We report on spectroscopy of the white-dwarf companion of the millisecond radio pulsar PSR J1012+5307. We find strong Balmer absorption lines, as would be expected for a cool DA wh…
Quantum Key Distribution and String Oblivious Transfer in Noisy Channels
Dominic Mayers
We prove the unconditional security of a quantum key distribution (QKD) protocol on a noisy channel against the most general attack allowed by quantum physics. We use the fact that…
More on Four-Dimensional Extremal Black Holes
N. Hambli
We consider an embedding of the extremal four-dimensional Reissner-Nordström black hole into type string theory. The equivalent type configuration, in the D-brane weak-…
Solitons in a Baby-Skyrme model with invariance under area preserving diffeomorphisms
T. Gisiger, M. B. Paranjape
We study the properties of soliton solutions in an analog of the Skyrme model in 2+1 dimensions whose Lagrangian contains the Skyrme term and the mass term, but no usual kinetic te…
Localized Mass and Spin Sources in 2+1 Dimensional Topologically Massive Gravity
A. Edery, M. B. Paranjape
Stationary solutions to the full non-linear topologically massive gravity (TMG) are obtained for localized sources of mass and spin . Our results show that the topological t…
Teleportation as a quantum computation
Gilles Brassard
An explicit quantum circuit is given to implement quantum teleportation. This circuit makes teleportation straightforward to anyone who believes that quantum computation is a reaso…
Tight bounds on quantum searching
Michel Boyer, Gilles Brassard, Peter Hoeyer +1
We provide a tight analysis of Grover's recent algorithm for quantum database searching. We give a simple closed-form formula for the probability of success after any given number…
q-Ultraspherical polynomials for q a root of unity
V. Spiridonov, A. Zhedanov
Properties of the -ultraspherical polynomials for being a primitive root of unity are derived using a formalism of the algebra. The orthogonality condition for the…
Information Gain vs. State Disturbance in Quantum Theory
Christopher A. Fuchs
The engine that powers quantum cryptography is the principle that there are no physical means for gathering information about the identity of a quantum system's state (when it is k…
