Polarization-resolved core exciton dynamics in LiF using attosecond transient absorption spectroscopy
The authors introduce here linear dichroism into attosecond transient absorption spectroscopy measurements to explore the orbital character of core exciton excited states in LiF thin films during their few-femtosecond exciton coherence lifetimes. The dichroic effect is well-described by atomic alignment angular momentum rules, which allow or forbid transitions from an aligned $p$-like state to a resonant $s$-like state, depending on the beam polarizations. A few-level model simulation and density functional theory calculations are used to corroborate the orbital character assignments of the core exciton states in the solid.
