Gauge-invariant absorption of light from a coherent superposition of states
Axel Stenquist, Felipe Zapata, Jan Marcus Dahlström
Absorption and emission of light is studied theoretically for excited atoms in coherent superposition of states subjected to isolated attosecond pulses in the extreme ultraviolet r…
Thomas--Reiche--Kuhn Correction for Truncated Configuration Interaction Spaces: Case of Laser-Assisted Dynamical Interference
Mattias Bertolino, Stefanos Carlström, Jasper Peschel +3
The Thomas--Reiche--Kuhn sum rule is used to form an effective potential that is added to the time-dependent configuration interaction singles (TDCIS) equations of motion in veloci…
Relativistic time-dependent configuration-interaction singles
Felipe Zapata, Jimmy Vinbladh, Anton Ljungdahl +2
In this work, a derivation and implementation of the relativistic time-dependent configuration interaction singles (RTDCIS) method is presented. Various observables for krypton and…
Complete characterization of multi-channel single photon ionization
Jasper Peschel, David Busto, Marius Plach +11
Ionization of atoms and molecules by absorption of a light pulse results in electron wavepackets carrying information on the atomic or molecular structure as well as on the dynamic…
Implementation and validation of the relativistic transient absorption theory within the dipole approximation
Felipe Zapata, Jimmy Vinbladh, Eva Lindroth +1
A relativistic transient absorption theory is derived, implemented and validated within the dipole approximation based on the time-dependent Dirac equation. Time-dependent simulati…
Propensity rules and interference effects in laser-assisted photoionization of helium and neon
Mattias Bertolino, David Busto, Felipe Zapata +1
We investigate the angle-resolved photoelectron spectra from laser-assisted photoionization for helium and neon atoms using an \textit{ab initio} method based on time-dependent sur…
