Distinguishing electronic and vibronic coherence in 2D spectra by their temperature dependence [PDF]
, 2013 Long-lived oscillations in 2D spectra of chlorophylls are at the heart of an ongoing debate. Their physical origin is either a multi-pigment effect, such as excitonic coherence, or primarily stems from localized vibrations.

Linear, third- and fifth-order nonlinear spectroscopy of a charge transfer system coupled to an underdamped vibration [PDF]
, 2015 We study hole, electron and exciton transport in a charge transfer system in the presence of underdamped vibrational motion. We analyze the signature of these processes in the linear and third-, and fifth-order nonlinear electronic spectra.

Distinctive character of electronic and vibrational coherences in disordered molecular aggregates
, 2013 Coherent dynamics of coupled molecules are effectively characterized by the two-dimensional (2D) electronic coherent spectroscopy. Depending on the coupling between electronic and vibrational states, oscillating signals of purely electronic, purely ...
