TL;DR: In this article, the authors investigate tunneling ionization of a model helium atom in a strong circularly polarized short laser pulse using the classical backpropagation method and compare ten different tunneling criteria on the same footing, aiming for a consistent classical picture of tunneling dynamics.

TL;DR: In this paper, the authors investigated the ionization dynamics of atoms irradiated by an intense laser field using a semiclassical model that includes magnetic Lorentz force in the rescattering process.

TL;DR: In this article, it was shown 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.

TL;DR: In this article, the authors studied the ionization dynamics of oriented polar molecules in strong elliptically polarized laser fields and showed that the excited-state channel is usually temporally delayed by a few hundred attoseconds in comparison with the ground-state one.

TL;DR: In this article, the authors theoretically investigate the electron-tunneling process for a helium atom irradiated by an elliptical strong laser field and find that the electron momentums along the minor axis of the laser polarization show good agreement with the nonadiabatic semiclassical calculation for a wide range of laser intensities, indicating the existence of a nonzero lateral momentum when the electron exits the barrier.
