Alternative gauge for the description of the light-matter interaction in a relativistic framework
Tor Kjellsson, Morten Førre, Aleksander Skjerlie Simonsen +2
We present a generalized velocity gauge form of the relativistic laser-matter interaction. In comparison with the (equivalent) regular minimal coupling description, this new form o…
Relativistic ionization dynamics for a hydrogen atom exposed to super-intense XUV laser pulses
Tor Kjellsson, Sølve Selstø, Eva Lindroth
We present a theoretical study of the ionization dynamics of a hydrogen atom exposed to attosecond laser pulses in the extreme ultra violet region at very high intensities. The pul…
High-redshift supernova rates measured with the gravitational telescope A1689
Tanja Petrushevska, Rahman Amanullah, Ariel Goobar +12
We present a ground-based near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z=0.18, one of the most powerful gravitational telescopes that nature…
Envelope induced ionization dynamics beyond the dipole approximation
Aleksander Skjerlie Simonsen, Tor Kjellsson, Morten Førre +2
When atoms and molecules are ionized by laser pulses of finite duration and increasingly high intensities, the validity of the much used dipole approximation, in which the spatial…
