The Type Ia Supernova Rate in Radio and Infrared Galaxies from the CFHT Supernova Legacy Survey
M. L. Graham, C. J. Pritchet, M. Sullivan +25
We have combined the large SN Ia database of the Canada-France-Hawaii Telescope Supernova Legacy Survey and catalogs of galaxies with photometric redshifts, VLA 1.4 GHz radio sourc…
The entanglement gap and a new principle of adiabatic continuity
R. Thomale, A. Sterdyniak, N. Regnault +1
We give a complete definition of the entanglement gap separating low-energy, topological levels, from high-energy, generic ones, in the "entanglement spectrum" of Fractional Quantu…
Tunneling-driven breakdown of the 331 state and the emergent Pfaffian and composite Fermi liquid phases
Z. Papic, M. O. Goerbig, N. Regnault +1
We examine the possibility of creating the Moore-Read Pfaffian in the lowest Landau level when the multicomponent Halperin 331 state (believed to describe quantum Hall bilayers and…
Photometric redshifts for supernovae Ia in the Supernova Legacy Survey
N. Palanque-Delabrouille, V. Ruhlmann-Kleider, S. Pascal +17
We present a method using the SALT2 light curve fitter to determine the redshift of Type Ia supernovae in the Supernova Legacy Survey (SNLS) based on their photometry in g', r', i'…
The ESO/VLT 3rd year Type Ia supernova data set from the Supernova Legacy Survey
C. Balland, S. Baumont, S. Basa +24
We present 139 spectra of 124 Type Ia supernovae (SNeIa) that were observed at the ESO/VLT during the first three years of the Canada-France-Hawai Telescope (CFHT) Supernova Legacy…
Photometric Calibration of the Supernova Legacy Survey Fields
N. Regnault, A. Conley, J. Guy +13
We present the photometric calibration of the Supernova Legacy Survey (SNLS) fields. The SNLS aims at measuring the distances to SNe Ia at (0.3<z<1) using MegaCam, the 1 deg^2 imag…
S3 Quantum Hall Wavefunctions
Steven H. Simon, E. H. Rezayi, N. Regnault
We construct a family of quantum Hall Hamiltonians whose ground states, at least for small system sizes, give correlators of the S3 conformal field theories. The ground states are…
Interaction-tuned compressible-to-incompressible phase transitions in the quantum Hall systems
Z. Papić, N. Regnault, S. Das Sarma
We analyze transitions between quantum Hall ground states at prominent filling factors in the spherical geometry by tuning the width parameter of the Zhang-Das Sarma interactio…
The Core-collapse rate from the Supernova Legacy Survey
G. Bazin, N. Palanque-Delabrouille, J. Rich +27
We use three years of data from the Supernova Legacy Survey (SNLS) to study the general properties of core-collapse and type Ia supernovae. This is the first such study using the "…
Clustering properties, Jack polynomials and unitary conformal field theories
Benoit Estienne, Nicolas Regnault, Raoul Santachiara
Recently, Jack polynomials have been proposed as natural generalizations of Z_k Read-Rezayi states describing non-Abelian fractional quantum Hall systems. These polynomials are con…
Optical phonon scattering and theory of magneto-polarons in a quantum cascade laser in a strong magnetic field
Yu Chen, N. Regnault, R. Ferreira +2
We report a theoretical study of the carrier relaxation in a quantum cascade laser (QCL) subjected to a strong magnetic field. Both the alloy (GaInAs) disorder effects and the Froh…
The Anatomy of Abelian and Non-Abelian Fractional Quantum Hall States
B. Andrei Bernevig, N. Regnault
We deduce a new set of symmetries and relations between the coefficients of the expansion of Abelian and Non-Abelian Fractional Quantum Hall (FQH) states in free (bosonic or fermio…
Fractional quantum Hall state at ν=1/4 in a wide quantum well
Z. Papic, G. Moller, M. V. Milovanovic +2
We investigate, with the help of Monte-Carlo and exact-diagonalization calculations in the spherical geometry, several compressible and incompressible candidate wave functions for…
Theoretical expectations for a fractional quantum Hall effect in graphene
Z. Papić, M. O. Goerbig, N. Regnault
Due to its fourfold spin-valley degeneracy, graphene in a strong magnetic field may be viewed as a four-component quantum Hall system. We investigate the consequences of this parti…
Topological Entanglement and Clustering of Jain Hierarchy States
N. Regnault, B. Andrei Bernevig, F. D. M. Haldane
We obtain the clustering properties and part of the structure of zeroes of the Jain states at filling : they are a direct product of a Vandermonde determinant (whic…
