TL;DR: Ultrafast optical spectroscopy with sub-20-fs time resolution and spectral coverage from the visible to the near-infrared allows us to follow the dynamics leading to the conical intersection in rhodopsin isomerization and finds excellent agreement between the experimental observations and molecular dynamics calculations that involve a true electronic state crossing.

TL;DR: The mechanisms controlling the ultrafast dynamics, in particular the role of collinear scattering, are identified, which gives rise to Auger processes, including charge multiplication, which is key in photovoltage generation and photodetectors.

TL;DR: A related phenomenon was proposed 40 years ago in which it is the ions in the crystal rather than the electrons that mediate the interaction as mentioned in this paper, which is known as ionic Raman scattering.

TL;DR: In this paper, the authors observed Rabi oscillations in a metal structure with a J-aggregate nonlinear medium and coherent energy transfer between excitonic quantum emitters and surface plasmons.

TL;DR: This work uses femtosecond transient absorption spectroscopy to monitor the relaxation dynamics of single-layer MoS2 over the entire visible range, and finds that, irrespective of excitation photon energy, the transient absorption spectrum shows the simultaneous bleaching of all excitonic transitions and corresponding red-shifted photoinduced absorption bands.
