Femtosecond Dynamics of the Exciton Self-Trapping Process in a Quasi-One-Dimensional Halogen-Bridged Platinum Complex

Nuclear wave-packet dynamics in the localized excitons of halogen-bridged platinum complexes

“…4, where the time origin and the intensity scale are not calibrated. The envelopes of the curves are in agreement with our previous results taken at a lower time resolution [4]. As for the oscillating component, the behavior is very similar to the PtBr system: At higher photon energies, the WP oscillation is clearly observed and the damping of the oscillation amplitude is fast.…”

Polaron dynamics with a multitude of Davydov D2 trial states

“…In photosynthesis, it is suggested that quantum coherence might play a significant role in achieving the remarkably high efficiency (> 95%) of the excitation energy transport [13][14][15], which can be studied by observing electronic superpositions and their evolution using 2D electronic spectroscopy techniques [13,14,16,17]. Emerging technological capabilities to control femtosecond pulse durations and down-to-one-hertz bandwidth resolutions provide novel probes on vibrational dynamics and excitation relaxation which were elusive in the past [18]. Recently, developments in ultrafast laser physics Figure 1: Schematic of the Holstein model.…”

Coexistence of excited polarons and metastable delocalized states in photoinduced metals

“…Signatures of strong electron-phonon coupling and polaronic effects in photo-excited systems have been found for the self-trapping of excitons [8][9][10][11], in Mott insulators [12,13], and organic materials [14][15][16]. A direct observation of the self-localization process was achieved by two-photon photoemission for electrons in surface states which couple to adsorbate layers [17][18][19][20].…”
