Adiabatic population transfer between electronic states of LiH molecule in two picosecond laser pulses

open access: yesAIP Advances, 2018
The population transfer of stimulated Raman adiabatic passage (STIRAP) is investigated using a time-dependent quantum wave packet method. The population is transferred from an initial state to a target state through the interaction of the external laser ...

Finite nuclear mass corrections to electric and magnetic interactions in diatomic molecules [PDF]

open access: yes, 2009
In order to interpret precise measurements of molecular properties the finite nuclear mass corrections to the Born-Oppenheimer approximation have to be accounted for. It is shown that they can be obtained systematically in the perturbative approach.

Electric dipole rovibrational transitions in HD molecule

open access: yes, 2008
The rovibrational electric dipole transitions in the ground electronic state of the HD molecule are studied. A simple, yet rigorous formula is derived for the transition rates in terms of the electric dipole moment function $D(R)$, which is calculated in

Phase-dependent decoherence of optical transitions in Pr3+:LaF3 in the presence of a driving field [PDF]

open access: yes, 2003
The decoherence times of orthogonally phased components of the optical transition dipole moment in a two-level system have been observed to differ by an order of magnitude.

Interaction induced ferro-electricity in the rotational states of polar molecules

open access: yes, 2010
We show that a ferro-electric quantum phase transition can be driven by the dipolar interaction of polar molecules in the presence a micro-wave field.

The effects of wetting layer on electronic and optical properties of intersubband P-to-S transitions in strained dome-shaped InAs/GaAs quantum dots

open access: yesAIP Advances, 2014
The authors report on the impact of wetting layer thickness and quantum dot size on the electronic and optical properties of dome-shaped InAs/GaAs quantum dots (QDs) with strained potential.

S-type Stars: Line List for the A2Π–X2Σ+ Band System of LaO

open access: yesThe Astrophysical Journal, 2023
LaO bands are found in the spectra of cool S-type stars. The bands of the A ^2 Π–X ^2 Σ ^+ transition with $v^{\prime} \leqslant 3$ and v ″ ≤ 4 are rotationally analyzed, providing spectroscopic constants for the A ^2 Π state.

Magnetophotoselection in the Investigation of Excitonically Coupled Chromophores: The Case of the Water-Soluble Chlorophyll Protein

open access: yesMolecules, 2022
A magnetophotoselection (MPS) investigation of the photoexcited triplet state of chlorophyll a both in a frozen organic solvent and in a protein environment, provided by the water-soluble chlorophyll protein (WSCP) of Lepidium virginicum, is reported ...
