  • Ultrafast diffraction is fundamental in capturing the structural dynamics of molecules. Here, the authors establish a variant of quantum state tomography for arbitrary degrees of freedom to characterize the molecular quantum states, which will enable the reconstruction of a quantum molecular movie from diffraction data.

  • The Jahn-Teller effect is the spontaneous symmetry breaking of the molecular structure caused by the coupling of electrons and nuclei. Here the authors use ultrafast Coulomb explosion imaging to map the evolution of the fundamental symmetry lowering process in photoionized methane within around 20fs.

  • Exciton-polariton transport in disordered organic media is simulated by quantum dynamics. The effects of static and dynamic disorder are disentangled, showing that static disorder primarily drives the transition to diffusive transport.

  • The Zundel [H(H2O)2]+ and Eigen [H(H2O)4]+ cations exhibit radicallly different infrared spectra and are the limiting dynamical structures involved in proton mobility in liquid water. Here, the authors find through quantum dynamics simulations that two polarized water molecules and a proton suffice to explain the key spectroscopic features connected to proton mobility for both species.

  • The carrier-envelope-phase of sub-cycle UV pulses strongly influences the dynamics of quantum systems, but its characterization is not accessible experimentally. Here, an asymmetry in the of angular photofragment distributions of diatomic molecules is identified as a way to imprint carrier-envelope-phase on a measurable quantity.

  • The timescale of isomerization in molecules involving ultrafast migration of constituent atoms is difficult to measure. Here the authors report that sub-100 fs isomerization time on acetylene dication in lower electronic states is not possible and point to misinterpretation of recent experimental results.

  • The full-quantum propagation of molecular degrees of freedom is onerous even for the capability of noisy intermediate-scale quantum devices (NISQ), and methods to perform mixed quantum-classical dynamics on NISQ devices are at an early stage of development. The authors present a modular algorithm to perform mixed quantum-classical dynamics NISQ devices.

  • The quantum excitation of photodissociation is restricted by the overlap between vibrational bound and continuum states. The authors manipulate the dynamics by generating new vibrational Fano resonances and controlling the asymmetric profiles of these resonances using an embedded ultraviolet pulse.

  • Resorting to resonant Auger spectroscopy mitigates the energy resolution limit of time-resolved X-ray photoelectron spectroscopy, but reconstructing the full nuclear wavepacket evolution from it is an open challenge. The authors retrieve the full information of a nuclear wavepacket from time-resolved resonant Auger spectroscopy measurements.
