Diatomic molecule in a strong infrared laser field: level-shifts and bond-length change due to laser-dressed Morse potential

Abstract

We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and field-induced terms and their gradients in the dipole moment function, and we derive analytic formulae for the bond-length change and for the shifted energy eigenvalues of the vibrations, by using the Kramers-Henneberger frame. We apply these results to the important cases of H2 and LiH, driven by a near- or mid-infrared laser in the 1013 W/cm2 intensity range.

Vibronic Correlations in Molecular Strong-Field Dynamics

“…However, setting one of these two terms to zero seems artificial, and thus, here we show the results of simulations including both contributions, which we called LBS. We mention that this model is very close to the one used in ref , where they give a fully analytical solution in the case of the Morse potential. Here we use a numerical approach that we can use for any chosen potential.…”

Approximate solutions for diatomic molecules under combined potentials in a global monopole and Aharonov–Bohm flux field

“…A qualitative understanding of all the important aspects of wavefunctions and energies of quantum particles can be developed by utilizing the SE of a physical system, like diatomic molecules. Over the years, numerous authors have exhibited interest in examining the SE's solutions with a variety of potential functions [1–19]. In these quantum mechanical problems, approximation procedures have been widely employed [1, 2, 4–7, 20–26] rather than exact methods [27] to find out bound state solutions of these SEs.…”
