Cosmological Parameters from the QUaD CMB polarization experiment
QUaD collaboration, P. G. Castro, P. Ade +29
In this paper we present a parameter estimation analysis of the polarization and temperature power spectra from the second and third season of observations with the QUaD experiment…
The 1+1 Dimensional Abelian Higgs Model Revisited: Physical Sector and Solitons
Laure Gouba, Jan Govaerts, M. Norbert Hounkonnou
In this paper the two dimensional abelian Higgs model is revisited. We show that in the physical sector, the solutions to the Euler-Lagrange equations include solitons.
The 1+1 Dimensional Abelian Higgs Model Revisited: Non-perturbative Dynamics in the Physical Sector
Laure Gouba, Jan Govaerts
In this paper the two dimensional Abelian Higgs model is revisited. We show that in the physical sector, this model describes the coupling of the electric field to the radial part,…
Classes of f-Deformed Landau Operators: Nonlinear Noncommutative Coordinates from Algebraic Representations
Joseph Ben Geloun, Jan Govaerts, M. N. Hounkonnou
We consider, in a superspace, new operator dependent noncommutative (NC) geometries of the nonlinear quantum Hall limit related to classes of f-deformed Landau operators in the sph…
A Deformation of Quantum Dynamics through the Phase Space Path Integral
Jan Govaerts, Olivier Mattelaer
Using a regularised construction of the phase space path integral due to Ingrid Daubechies and John Klauder which involves a time scale ultimately taken to vanish, and motivated by…
VLT/FORS1 spectrophotometry of the first planetary nebula discovered in the Phoenix dwarf galaxy
Ivo Saviane, Katrina Exter, Yiannis Tsamis +2
Context: A planetary nebula (PN) candidate was discovered during FORS imaging of the Local Group dwarf galaxy Phoenix. Aims: Use this PN to complement abundances from red-giant sta…
