Robust transverse structures in rescattered photoelectron wave packets and their observable consequences
Robust transverse structures in rescattered photoelectron wave packets and their observable consequences
Initial-state symmetry has been underappreciated in strong-field spectroscopies, where laser fields dominate the dynamics. We demonstrate numerically that the transverse photoelectron phase structure arising from this symmetry is robust in strong-field rescattering and manifests in strong-field photoelectron spectra. Interpretation of rescattering experiments need to take these symmetry effects into account. …
