Diversity of coherences and origin of electronic transitions of supermolecular nanoring
Vytautas Butkus, Jan Alster, Eglė Bašinskaitė +6
Quantum coherence is highly involved in photochemical functioning of complex molecular systems. Co-existence and intermixing of electronic and/or vibrational coherences, while neve…
Coherence and population dynamics of chlorophyll excitations in FCP complex: Two-dimensional spectroscopy study
Vytautas Butkus, Andrius Gelzinis, Ramūnas Augulis +6
The energy transfer processes and coherent phenomena in the fucoxanthin-chlorophyll protein complex, which is responsible for the light harvesting function in marine algae diatoms,…
Vibronic phenomena and exciton-vibrational interference in two-dimensional spectra of molecular aggregates
Vytautas Butkus, Leonas Valkunas, Darius Abramavicius
A general theory of electronic excitations in aggregates of molecules coupled to intramolecular vibrations and the harmonic environment is developed for simulation of the third-ord…
Distinctive character of electronic and vibrational coherences in disordered molecular aggregates
Vytautas Butkus, Donatas Zigmantas, Darius Abramavicius +1
Coherent dynamics of coupled molecules are effectively characterized by the two-dimensional (2D) electronic coherent spectroscopy. Depending on the coupling between electronic and…
Molecular vibrations-induced quantum beats in two-dimensional electronic spectroscopy
Vytautas Butkus, Leonas Valkunas, Darius Abramavicius
Quantum beats in nonlinear spectroscopy of molecular aggregates are often attributed to electronic phenomena of excitonic systems, while nuclear degrees of freedom are commonly inc…
Vibrational vs. electronic coherences in 2D spectrum of molecular systems
Vytautas Butkus, Donatas Zigmantas, Leonas Valkunas +1
The two-dimensional spectroscopy has recently revealed oscillatory behavior of excitation dynamics in molecular systems. However, in the majority of cases it is strongly debated if…
