IONIZATION IN A 1-DIMENSIONAL DIPOLE MODEL

Ionization in a 1-Dimensional Dipole Model

We study the evolution of a one dimensional model atom with δfunction binding potential, subjected to a dipole radiation field E(t)x with E(t) a 2π/ω-periodic real-valued function. Starting with ψ(x, t = 0) an initially localized state and E(t) a trigonometric polynomial, complete ionization occurs; the probability of finding the electron in any fixed region goes to zero. For ψ(x, 0) compactly ...

Classical threshold behaviour in a 1+1-dimensional model for double ionization in strong fields

Building on insights about the classical pathways to double ionization in strong laser fields we here propose a 1+1-dimensional model that captures essentials of the 3-d potential landscape and allows efficient studies of the process in reduced dimensions. The reduction to one degree of freedom for each electron is obtained by confining their motion to lines at an angle of π/6 with respect to t...

ionization of a 1-d model of h2 + from different states in intense laser field*

time-dependent schrödinger equation for a 1-d model of hydrogen molecular ion h2+ in intenselaser field linearly polarized along the molecular axis is solved. ionization rates are calculated for differentinitial states. the evolution of electronic wavefunction at fixed inter-nuclear separations are simulated andanalyzed. the results obtained for the ground state of this 1-d model of h2+ show ap...
