研究目的
Investigating the occurrence of electron momentum vortices in single-photon double ionization of H2 by time-delayed, counter-rotating, elliptically polarized attosecond pulses.
研究成果
The study predicts the occurrence of kinematical and dynamical electron vortices in the double photoionization of H2 by attosecond pulses, depending on the orientation of the laser propagation direction relative to the molecular axis. It also proposes a method for a complete experiment to determine the magnitudes and relative phase of the dynamical amplitudes involved.
研究不足
The study is theoretical and relies on numerical simulations. Experimental validation is suggested but not provided within the paper.
1：Experimental Design and Method Selection:
The study is based on ab initio numerical solutions of the six-dimensional time-dependent Schr?dinger equation (TDSE) and analytic perturbation theory (PT) analyses.
2：Sample Selection and Data Sources:
The study focuses on the H2 molecule in its 1(cid:2)+ g ground state.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned in the paper.
4：Experimental Procedures and Operational Workflow:
The study involves solving the TDSE for H2 interacting with chiral pulses, with specific attention to two cases: ?k (cid:2) R and ?k ⊥ R.
5：Data Analysis Methods:
The analysis includes examining the momentum distributions of the two ionized electrons and proposing a complete experiment for determining the magnitudes and relative phases of the dynamical amplitudes involved.
