Recently, nuclear vibrational contribution signatures in two-dimensional (2D) electronic spectroscopy have attracted considerable interest, in particular as regards interpretation of the oscillatory transients observed in light-harvesting complexes. These transients have dephasing times that persist for much longer than theoretically predicted electronic coherence lifetime. As a plausible explanation for this long-lived spectral beating in 2D electronic spectra, quantum-mechanically mixed… 

Influence of weak vibrational-electronic couplings on 2D electronic spectra and inter-site coherence in weakly coupled photosynthetic complexes.

This work calculates the correlation between optical pump interactions and subsequent entanglement between sites, as measured by the concurrence, and compares the calculated 2D spectra with the site-probe response, and shows that an on-resonance vibration with Huang-Rhys factor as small as S = 0.005 and the most strongly coupled off-Resonance vibrations give rise to long-lived, purely vibrational coherences at 77 K.

Signatures of vibronic coupling in two-dimensional electronic-vibrational and vibrational-electronic spectroscopies.

A system Hamiltonian is developed here to lay a foundation for interpreting the 2D EV and 2D VE signals that arise from a vibronically coupled molecular system in the condensed phase and explores how these vibronic interactions are manifested in the positions, amplitudes, and line shapes of the peaks in 2D EVs and VE spectroscopies.

A method for the direct measurement of electronic site populations in a molecular aggregate using two-dimensional electronic-vibrational spectroscopy.

This work derives response functions for the 2DEV spectrum of a molecular dimer and proposes a method by which 2DEV spectra could be used to directly measure the electronic site populations as a function of time following the initial electronic excitation.

Two-Dimensional Electronic-Vibrational Spectroscopy of Coupled Molecular Complexes: A Near-Analytical Approach.

Although the interpretation of 2DEV spectra is considerably more complex than that for weakly coupled systems, the richness of the spectra and the necessity to consider both visible and infrared transition moments suggest that such analysis will be very valuable in characterizing the role of vibronic effects in ultrafast molecular dynamics.

Electronic energy transfer through non-adiabatic vibrational-electronic resonance. I. Theory for a dimer.

A generalized dimer model incorporates asymmetries between pigments, coupling to the environment, and the doubly excited state relevant for nonlinear spectroscopy, and shows that anti-correlated vibrations increase the range and speed of vibronically resonant energy transfer.

Theoretical study of excitation energy transfer and nonlinear spectroscopy of photosynthetic light‐harvesting complexes using the nonperturbative reduced dynamics method

The highly efficient excitation energy transfer (EET) processes in photosynthetic light‐harvesting complexes have attracted much recent research interests. Experimentally, spectroscopic studies have

Effects of Different Quantum Coherence on the Pump-Probe Polarization Anisotropy of Photosynthetic Light-Harvesting Complexes: A Computational Study.

Three model dimer systems with different prespecified quantum coherence are simulated, and the results show that their different spectral characteristics can be used to determine the type of coherence during the spectral process.

Effect of high-frequency modes on singlet fission dynamics.

It is demonstrated that fission dynamics strongly depends on the frequency of the intramolecular vibrational mode, and the effect of two vibrational modes on fissions dynamics is examined.

Fluctuations in Electronic Energy Affecting Singlet Fission Dynamics and Mixing with Charge-Transfer State: Quantum Dynamics Study.

The overall behavior of the dynamics is insensitive to values of the reorganization energy associated with the transition from the singlet state to the CT state, although the coherent oscillation is affected by the fluctuations, which indicates that the mixing with theCT state is rather robust under the fluctuations in the energy of the CTState as well as the high-lying CT state.

The role of resonant nuclear modes in vibrationally assisted energy transport: The LHCII complex.

It is conclusively show that resonant vibrations are capable of boosting the incoherent population relaxation pathways and cause rapid decoherence in light-harvesting complexes.



Origin of long-lived oscillations in 2D-spectra of a quantum vibronic model: electronic versus vibrational coherence.

These results link recently proposed microscopic, non-equilibrium mechanisms to support long lived coherence at ambient temperatures with actual experimental observations of oscillatory behaviour using 2D photon echo techniques to corroborate the fundamental importance of the interplay of electronic and vibrational degrees of freedom in the dynamics of light harvesting aggregates.

Two-dimensional spectroscopy of electronic couplings in photosynthesis

This work directly measures electronic couplings in a molecular complex, the Fenna–Matthews–Olson photosynthetic light-harvesting protein, and finds distinct energy transport pathways that depend sensitively on the detailed spatial properties of the delocalized excited-state wavefunctions of the whole pigment–protein complex.

Vibronic enhancement of exciton sizes and energy transport in photosynthetic complexes.

Investigation of the impact of vibronic couplings on the electronic structures and relaxation mechanisms of two cyanobacterial light-harvesting proteins suggests that the distinct behaviors of these closely related proteins are understood on the same footing only in a basis of joint electronic-nuclear states.

Non-classicality of the molecular vibrations assisting exciton energy transfer at room temperature

In prototype dimers present in a variety of photosynthetic antennae, efficient vibration-assisted energy transfer in the sub-picosecond timescale and at room temperature can manifest and benefit from non-classical fluctuations of collective pigment motions.

Two-dimensional spectroscopy of a molecular dimer unveils the effects of vibronic coupling on exciton coherences.

This work presents measurements and calculations on a solvated molecular homodimer with clearly resolvable oscillations in the corresponding two-dimensional spectra and finds that although calculations predict a prolongation of this coherence due to vibronic coupling, the combination of dynamic disorder and vibrational relaxation leads to a coherence decay on a timescale comparable to the electronic dephasing time.

Enhancement of Vibronic and Ground-State Vibrational Coherences in 2D Spectra of Photosynthetic Complexes

A vibronic-exciton model is applied to investigate the recently proposed mechanism of enhancement of coherent oscillations due to mixing of electronic and nuclear degrees of freedom and concludes that both type of coherences have a similar magnitude at longer population time.

High frequency vibrational modulations in two-dimensional electronic spectra and their resemblance to electronic coherence signatures.

The results show that these anticorrelated oscillations occur for vibrational wavepackets and not exclusively for electronic coherences as has been assumed previously.

Previous two-dimensional electronic spectroscopy investigations of the FMO bacteriochlorophyll complex are extended, and direct evidence is obtained for remarkably long-lived electronic quantum coherence playing an important part in energy transfer processes within this system is obtained.

Origin of Long-Lived Coherences in Light-Harvesting Complexes

A vibronic exciton model is applied to explain the long-lived oscillatory features in the two-dimensional electronic spectra of the Fenna–Matthews–Olson (FMO) complex and predicts oscillations with dephasing times of 1.3 ps at 77 K, which is in a good agreement with the experimental results.
