Incorporating real time velocity map image reconstruction into closed-loop coherent control

“…While our initial work focused on photodissociation, in principle, this method may be applied to any laser-driven system that can be measured using an imaging technique. Some interesting possibilities include rescattering electrons, 62,63 nanoplasmas, 64 nanodroplets, 65 laserinduced molecular motions 66 and excitations, 67 and finally the possibility of one day using laser-induced electron diffraction of molecules 62,68 or photoelectron tomography 69 as control targets. Given the general applicability of 3D-VMI feedback and the context-rich information that can be gleaned from these images, there are undoubtedly additional directions that might be explored, especially in more complex systems.…”

A multi-agent quantum Monte Carlo model for charge transport: Application to organic field-effect transistors

“…[75][76][77][78][79][80] The coupling of ESI with PES allowed MCAs to be spectroscopically characterized for the first time. [4][5][6][32][33][34][35][36][37][38][39][40] When an electron is detached from a MCA, it experiences a short-range attraction by the nuclei and a long-range repulsion from the negatively charged residual ion, resulting in the socalled RCB (Fig. 2(a)).…”

“…A number of reviews and perspectives on the PES of MCAs have appeared; [32][33][34][35][36] and this perspective focuses on more recent advances. The article is organized as follows.…”

Time-Resolved Photodetachment Anisotropy: Gas-Phase Rotational and Vibrational Dynamics of the Fluorescein Anion

“…We have also performed our experiments under "colder" conditions which revealed that the rotational dephasing indeed slows down to t min ~ 3 ps, corresponding to an internal temperature of T ~ 300 K (see supporting information). 38,39 A full analysis of the rotational dephasing would allow an accurate determination of the rotational constants of a molecular system from τ r , 37 however, as this requires an accurate determination of the internal temperature, such an analysis is beyond the scope of this study. In TR-FA, τ r can be related to the local viscosity of the solvent, which is clearly not appropriate for a gas-phase experiment.…”
