Directly revealing the geometric phase effect of dissociative D₂⁺by two-color strong field photodissociation

with the random orientation by solving the time-dependent Schrödinger equation. We reveal the GP effect that manifests as the Aharonov-Bohm-like interference in the photofragment angular distribution along the direction perpendicular to the linear polarization axis. Our work deepens the understanding of the physical mechanisms of the molecular dynamics when driven by the synthesized strong laser field.
