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

Femtosecond nonlinear spectroscopy is the main tool for the time-resolved detection of
photophysical and photochemical processes. Since most systems of chemical interest are …

The motion of chemical bonds within molecules can be observed in real time in the form of
vibrational wave packets prepared and interrogated through ultrafast nonlinear …

The detection of individual molecules has found widespread application in molecular
biology, photochemistry, polymer chemistry, quantum optics and super-resolution …

We present a review on the advances of pulse control and ultrafast coherent excitation of
both plasmonic nanoantennas and individual molecular systems, primarily based on the …

Two-dimensional infrared (2D-IR) spectroscopy provides powerful tools to investigate
chemical reaction dynamics in the condensed phase. Correlating excitation and detection …

Ultrafast two-pulse experiments on single molecules are invaluable tools to investigate the
microscopic dynamics of a fluorophore. The first pulse generates electronic or vibronic …

Understanding the quantum coherence effects is crucial for their promising applications,
such as engineering artificial photosynthesis, manipulating chemical reactions, and …

We develop a first principles theoretical description of femtosecond double-pump single-
molecule signals of molecular aggregates. We incorporate all singly excited electronic states …

The present paper is devoted to the simulation of (integral and dispersed) pump–probe
signals in the nonperturbative regime for a series of material systems with multiple electronic …
