State-correlated reaction dynamics unveiled in full from a single product-image measurement [PDF]

open access: yesNature Communications
Electron- or photoionization mass spectrometry coupled with product time-of-flight measurement is a universal detection scheme, which has been playing pivotal role in advancing our fundamental understanding of chemical reactions.

Reaction Dynamics with Exotic Nuclei [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2002
Abstract We review the new possibilities offered by the reaction dynamics of asymmetric heavy-ion collisions, using stable and unstable beams. We show that it represents a rather unique tool to probe regions of highly asymmetric nuclear matter (ANM) in compressed as well as dilute phases, and to test the in-medium isovector interaction for high ...

Reaction-Limited Quantum Reaction-Diffusion Dynamics

open access: yesPhysical Review Letters, 2023
We consider the quantum nonequilibrium dynamics of systems where fermionic particles coherently hop on a one-dimensional lattice and are subject to dissipative processes analogous to those of classical reaction-diffusion models. Particles can either annihilate in pairs, $A+A \to \emptyset$, coagulate upon contact, $A+A \to A$, and possibly also branch,

Singlet fission dynamics modulated by molecular configuration in covalently linked pyrene dimers, Anti- and Syn-1,2-di(pyrenyl)benzene

open access: yesCommunications Chemistry, 2023
Singlet fission excited-state relaxation, as observed in covalently linked dimers, could allow energy-conversion efficiencies in photovoltaic devices beyond the Shockley–Queisser limit. Here, the authors study the effect of the molecular configuration of

Excitonic Bloch–Siegert shift in CsPbI3 perovskite quantum dots

open access: yesNature Communications, 2022
Observation of a Bloch-Siegert shift has remained elusive. Here, Wu et al, reports spin-selective Bloch-Siegert shift in lead halide perovskite quantum dots, and highlights the importance of many-body interactions in correctly modeling the shift.

Spin blockade and phonon bottleneck for hot electron relaxation observed in n-doped colloidal quantum dots

open access: yesNature Communications, 2021
Hot electrons in bulk semiconductors usually relax via electron-phonon scattering on a sub-picosecond timescale. Here, the authors observe hot electron lifetime as long as 320 picoseconds by performing a photochemical reduction reaction on colloidal ...

Ultraviolet photolysis of H2S and its implications for SH radical production in the interstellar medium

open access: yesNature Communications, 2020
Sulfur is abundant in the Universe, but the observed abundance ratio of SH to H2S doesn’t agree with astrochemical models. The authors measure product state-resolved translational energy spectra of photoproducts in a jet-cooled H2S beam as a function of ...

Transition manifolds of complex metastable systems: Theory and data-driven computation of effective dynamics [PDF]

open access: yes, 2017
We consider complex dynamical systems showing metastable behavior but no local separation of fast and slow time scales. The article raises the question of whether such systems exhibit a low-dimensional manifold supporting its effective dynamics.
