Strong-field laser–molecule interaction forms much of the basis for initiating and probing
ultrafast quantum dynamics. Previous studies aimed at elucidating the origins of vibrational …

In this perspective, we discuss how one can initiate, image, and disentangle the ultrafast
elementary steps of thermal-energy chemical dynamics, building upon advances in …

We investigate the ultrafast vibronic dynamics triggered by intense femtosecond infrared
pulses in small molecules. Our study is based on numerical simulations performed with 2D …

A comparative study of bond rearrangement is reported for the double ionization of three
triatomic molecules: carbon dioxide, carbonyl sulfide, and water (D 2 O). Specifically, we …

Electronic coherences in molecules are ultrafast charge oscillations on the molecular frame
(MF) and their direct observation and separation from electronic population dynamics is …

CO 2 single-photon double photoionization, Coulomb explosion, and dissociative ionization
are studied with ultrafast extreme-ultraviolet pump and time-delayed near-infrared probe …

Ultrafast laser excitation can create coherent superpositions of electronic states in molecules
and trigger ultrafast flow of electron density on a few femtosecond timescale. While recent …

In this work, we experimentally study the angle-dependent single ionization of carbon
dioxide (CO 2) by linearly and circularly polarized pulses. The angle dependence of the …

We propose a scheme based on perturbation theory to reconstruct a molecular density
matrix (DM) using the pump-probe state-resolved energy spectra. By applying the scheme to …

Disentangling sequential and concerted three-body fragmentation has been a longstanding
endeavor in studies of molecular dynamics. To accomplish this goal, we recently introduced …
