Ponderomotive potential effects on strong field two-photon double ionization in neon
In the context of the recently reported experiment on photoionization in neon atom, we theoretically study the photoionization of neon atom at a comparatively intense laser field. The calculated photoelectron spectrum for a Gaussian laser pulse show an…

Analytical expression for continuum–continuum transition amplitude of hydrogen-like atoms with angular-momentum dependence
Attosecond chronoscopy typically utilises interfering two-photon transitions to access the phase information. Simulating these two-photon transitions is challenging due to the continuum–continuum transition term. The hydrogenic approximation within sec…
