Title: Quantum Interference of Glory Rescattering in Strong-Field Atomic Ionization,
Abstract: During the ionization of atoms irradiated by linearly polarized intense laser
fields, we find for the first time that the transverse momentum distribution of
photoelectrons can be well fitted by a squared zeroth-order Bessel function
because of the quantum interference effect of Glory rescattering. The
characteristic of the Bessel function is determined by the common angular
momentum of a bunch of semiclassical paths termed as Glory trajectories, which
are launched with different nonzero initial transverse momenta distributed on a
specific circle in the momentum plane and finally deflected to the same
asymptotic momentum, which is along the polarization direction, through
post-tunneling rescattering. Glory rescattering theory (GRT) based on the
semiclassical path-integral formalism is developed to address this effect
quantitatively. Our theory can resolve the long-standing discrepancies between
existing theories and experiments on the fringe location, predict the sudden
transition of the fringe structure in holographic patterns, and shed light on
the quantum interference aspects of low-energy structures in strong-field
atomic ionization.
