Attosecond delays between dissociative and non-dissociative ionization of polyatomic molecules [PDF]

open access: yesNature Communications, 2023
The interplay between electronic and nuclear motions in molecules is a central concept in molecular science. To what extent it influences attosecond photoionization delays is an important, still unresolved question. Here, we apply attosecond electron-ion

Coherent atomic orbital polarization probes the geometric phase in photodissociation of polyatomic molecules

open access: yesNatural Sciences, 2022
Quantum interference between multiple pathways in molecular photodissociation often results in angular momentum polarization of atomic products and this can give deep insight into fundamental physical processes.

Prospects for laser cooling of polyatomic molecules with increasing complexity

open access: yesPhysical Review Research, 2020
Optical cycling transitions and direct laser cooling have recently been demonstrated for a number of alkaline-earth dimers and trimer molecules. This is made possible by diagonal Franck-Condon factors between the vibrational modes of the optical ...

Characterizing the fundamental bending vibration of a linear polyatomic molecule for symmetry violation searches

open access: yesNew Journal of Physics, 2023
Polyatomic molecules have been identified as sensitive probes of charge-parity violating and parity violating physics beyond the Standard Model (BSM). For example, many linear triatomic molecules are both laser-coolable and have parity doublets in the ...
