The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

An open quantum system refers to a system that is further coupled to a bath system
consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is …

Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with
fixed phase differences. Although coherence has been shown to yield transformative ways …

Conspectus The transport and photophysical properties of organic molecular aggregates,
films, and crystals continue to receive widespread attention, driven mainly by expanding …

Resonance energy transfer (RET), the transport of electronic energy from one atom or
molecule to another, has significant importance to a number of diverse areas of science …

Insights from spectroscopic experiments led to the development of quantum mechanics as
the common theoretical framework for describing the physical and chemical properties of …

Electrons are the workhorses of solar energy conversion. Conversion of the energy of light to
electricity in photovoltaics, or to energy-rich molecules (solar fuel) through photocatalytic …

Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …
