Measuring the continuum polarization with ESPaDOnS
(European Southern Observatory, 2015)
Aims. Our goal is to test the feasibility of obtaining accurate measurements of the continuum polarization from high-resolution spectra using the spectropolarimetric mode of ESPaDOnS. Methods. We used the new pipeline OPERA ...
On a conjecture by Mbekhta about best approximation by polar factors
(American Mathematical Society, 2021-11)
The polar factor of a bounded operator acting on a Hilbert space is the unique partial isometry arising in the polar decomposition. It is well known that the polar factor might not be a best approximant to its associated ...
The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
(2002-12-01)
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...

A model for the competition between political mono-polarization and bi-polarization
(American Institute of Physics, 2020-06)
We investigate the phenomena of political bi-polarization in a population of interacting agents by means of a generalized version of the model introduced by Vazquez et al. [Phys. Rev. E 101, 012101 (2020)] for the dynamics ...
3D radiative transfer of intrinsically polarized dust emission based on aligned aspherical grains
(Oxford University Pres, 2017)
(Sub-)millimetre observations of the polarized emission of aligned aspherical dust grains enable us to study the magnetic fields within protoplanetary disc. However, the interpretation of these observations is complex. One ...
