Comparison between Jacobi-Anger and saddle point methods to treat Above-threshold ionization
Danish Furekh Dar, Stephan Fritzsche
We present a detailed comparison of theoretical approaches for modeling strong-field ionization by few-cycle laser pulses. The dipole approximation is shown to accurately capture i…

Nondipole strong-field approximation for above threshold ionization in few-cycle pulse
Danish Furekh Dar, Björn Minneker, Stephan Fritzsche
The ionization of atoms and molecules by strong laser fields has been studied extensively, both theoretically and experimentally. The strong-field approximation (SFA) allows for th…

Radiative Transition Properties of Singly Charged Magnesium, Calcium, Strontium and Barium Ions
Mandeep Kaur, Danish Furekh Dar, B. K. Sahoo +1
Accurate values of electric dipole (E1) amplitudes along with their uncertainties for a number of transitions among low-lying states of Mg, Ca, Sr, and Ba are liste…
