Faurobert, M., Derouich, M., Bommier, V., Arnaud, J.
The physics of the solar chromosphere depends in a crucial way on its magnetic structure. However there are presently very few direct magnetic field diagnostics available for this region. Here we...
First Direct Detection of Magnetic Fields in Starspots and Stellar Chromospheres (2007)
Berdyugina, S. V., Fluri, D. M., Afram, N., Suwald, F., Petit, P., Arnaud, J., ...
Here we report on the first detection of circular polarization in molecular lines formed in cool magnetic regions (starspots) and in chromospheric emission lines formed in hot plages on the surfaces...
Detection of the Molecular Zeeman Effect in Circular Polarization on Cool Active Stars (2007)
Berdyugina, S. V., Petit, P., Fluri, D. M., Afram, N., Arnaud, J.
We report on the first ever detection of circular polarization in molecular lines forming in magnetic regions on the surfaces of active stars. The new observations were obtained with the...
Arnaud, J., Chusseau, L., Philippe, F.
Quiet (or sub-Poissonian) oscillators generate a number of dissipation events whose variance is less than the mean. It was shown in 1984 by Golubev and Sokolov that lasers driven by regular pumps are...

Monte Carlo Simulation of Laser Diodes Sub-Poissonian Light Generation (2006)
When laser diodes are driven by high-impedance electrical sources the variance of the number of photo-detection events counted over large time durations is less than the average number of events...

Carnot cycle for an oscillator (2005)
Arnaud, J., Chusseau, L., Philippe, F.
Carnot established in 1824 that the efficiency of cyclic engines operating between a hot bath at absolute temperature $T_{hot}$ and a bath at a lower temperature $T_{cold}$ cannot exceed...
Fluorescence from a few electrons (2005)
Arnaud, J., Chusseau, L., Philippe, F.
Systems containing few Fermions (e.g., electrons) are of great current interest. Fluorescence occurs when electrons drop from one level to another without changing spin. Only electron gases in a...
Formation flyers applied to solar coronal observations: theASPICS mission (2005)
Vives, S., Lamy, P., Auchere, F., Koutchmy, S., Arnaud, J., ...
Classical externally-occulted coronagraphs are presently limited in their performances by the distance between the external occulter and the front objective. The diffraction fringe from the occulter...
On the predominance of the radial component of the magnetic field in the solar corona (2004)
Habbal, S. R., Woo, R., Arnaud, J.
In this paper, the polarized intensity measurements of the Fe XIII 10747 A line described by Arnaud are placed, for the first time, in the context of the corresponding pB images from the HAO Mauna...

Are eukaryotic microorganisms clonal or sexual? A population genetics vantage.
Tibayrenc, M, Kjellberg, F, Arnaud, J, Oury, B, Brenière, S F, Dardé, M L, ...
We argue that the mode of reproduction of microorganisms in nature can only be decided by population genetic information. The evidence available indicates that many parasitic protozoa and unicellular...
