Determination of Beam Polarization for Optimal Gauge Boson Discovery Limits
Ali A. Bagneid
Extra neutral gauge bosons suggested by models beyond the standard model can indirectly show up in collisions through off-resonance deviations of various physical obs…
Stark widths of Ar III spectral lines in the atmospheres of subdwarf B stars
Rafik Hamdi, Nabil Ben Nessib, Sylvie Sahal-Bréchot +1
Using semiclassical perturbation approach in impact approximation, we have calculated Stark widths for 32 spectral lines of doubly charged argon (Ar III). Oscillator strengths are…
Quantum Stark broadening of Ar XV lines. Strong collision and quadrupolar potential contributions
Haykel Elabidi, Sylvie Sahal-Bréchot, Milan S Dimitrijević
We present in this paper electron impact broadening for six Ar XV lines using our quantum mechanical formalism and the semiclassical perturbation one. Additionally, our calculation…
Structural and collisional data for Mg III and Al IV
Haykel Elabidi
We present in this work energy levels, oscillator strengths, radiative decay rates and fine structure collision strengths for the Mg III and Al IV ions. The 11 configurations:(1s$^…
Remarks on the tensor degree of finite groups
Ahmad M. A. Alghamdi, Francesco G. Russo
The present paper is a note on the tensor degree of finite groups, introduced recently in literature. This numerical invariant generalizes the commutativity degree through the noti…
Terahertz dielectric response and coupled dynamics of ferroelectrics and multiferroics from effective Hamiltonian simulations
Dawei Wang, Jeevaka Weerasinghe, Abdullah Albarakati +1
Ferroelectric and multiferroic materials form an important class of functional materials. Over the last twenty years, first-principles-based effective Hamiltonian approaches have b…
