A Fortran General-Purpose Transpiler: Proof of Concept
Shivamshan Sivanesan, Kazem Ardaneh
Fortran has been the cornerstone of high-performance computing for decades and remains unmatched in many domains. Yet the language faces an expertise gap: a new generation of scien…
IPSL-AID: Generative Diffusion Models for Climate Downscaling from Global to Regional Scales
Kishanthan Kingston, Olivier Boucher, Freddy Bouchet +5
Effective adaptation and mitigation strategies for climate change require high-resolution projections to inform strategic decision-making. Conventional global climate models, which…
Femtosecond laser-induced sub-wavelength plasma inside dielectrics: III. Terahertz radiation emission
Kazem Ardaneh, Ken-Ichi Nishikawa, Remo Giust +5
Electromagnetic radiation within the terahertz (THz) frequency range is of great interest for applications in remote sensing and time-domain spectroscopy. The laser-induced plasmas…
Electron heating and radiation in high aspect ratio sub-micron plasma generated by an ultrafast Bessel pulse within a solid dielectric
Kazem Ardaneh, Remo Giust, Pierre-Jean Charpin +2
When propagating inside dielectrics, an ultrafast Bessel beam creates a high aspect-ratio cylinder of plasma with nanometric diameter that extends over several tens of micrometers…
Femtosecond laser-induced sub-wavelength plasma inside dielectrics: II. Second-harmonic generation
Kazem Ardaneh, Mostafa Hassan, Benoit Morel +5
Second-harmonic emission at a frequency that is twice the laser frequency is an important diagnostic for nonlinear laser-plasma interaction. It is forbidden for centrosymmetric mat…
Femtosecond laser-induced sub-wavelength plasma inside dielectrics: I. Field enhancement
Kazem Ardaneh, Remi Meyer, Mostafa Hassan +5
The creation of high energy density ( joules per cm) over-critical plasmas in a large volume has essential applications in the study of warm dense matter, being pr…

Kazem Ardaneh, Remi Meyer, Mostafa Hassan +9
We demonstrate for the first time to our knowledge the generation of overcritical plasma densities inside transparent solids over long distances using femtosecond laser pulses. Thi…
Generation of a Bessel beam in FDTD using a cylindrical antenna
Kazem Ardaneh, Remo Giust, Benoit Morel +1
Bessel beams are becoming a very useful tool in many areas of optics and photonics, because of the invariance of their intensity profile over an extended propagation range. Finite-…
A solver based on pseudo-spectral analytical time-domain method for the two-fluid plasma model
B. Morel, R. Giust, K. Ardaneh +1
A number of physical processes in laser-plasma interaction can be described with the two-fluid plasma model. We report on a solver for the three-dimensional two-fluid plasma model…
