Dark energy constraints and correlations with systematics from CFHTLS weak lensing, SNLS supernovae Ia and WMAP5
M. Kilbinger, K. Benabed, J. Guy +15
We combine measurements of weak gravitational lensing from the CFHTLS-Wide survey, supernovae Ia from CFHT SNLS and CMB anisotropies from WMAP5 to obtain joint constraints on cosmo…
Quantum Hall quasielectrons - Abelian and non-Abelian
T. H. Hansson, M. Hermanns, N. Regnault +1
The quasiparticles in Quantum Hall liquids carry fractional charge and obey fractional quantum statistics. Of particular recent interest are those with non-Abelian statistics, sinc…
The effect of progenitor age and metallicity on luminosity and 56Ni yield in Type Ia supernovae
D. A. Howell, M. Sullivan, E. F. Brown +23
Timmes, Brown & Truran found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized in Type Ia supernovae (SNe Ia), and thus ac…
PHotometry Assisted Spectral Extraction (PHASE) and identification of SNLS supernovae
S. Baumont, C. Balland, P. Astier +7
Aim: We present new extraction and identification techniques for supernova (SN) spectra developed within the Supernova Legacy Survey (SNLS) collaboration. Method: The new spectral…
Entanglement signatures of quantum Hall phase transitions
Oleksandr Zozulya, Masudul Haque, Nicolas Regnault
We study quantum phase transitions involving fractional quantum Hall states, using numerical calculations of entanglements and related quantities. We tune finite-size wavefunctions…
Pairing in ultracold Fermi gases in the lowest Landau level
G. Moller, Th. Jolicoeur, N. Regnault
We study a rapidly rotating gas of unpolarized spin-1/2 ultracold fermions in the two-dimensional regime when all atoms reside in the lowest Landau level. Due to the presence of th…
