Two-dimensional electronic spectroscopy (2DES) is a popular technique that can track
ultrafast coherent and incoherent processes in real time. Since its development in the late …

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

Singlet fission is the spin-allowed conversion of a spin-singlet exciton into a pair of spin-
triplet excitons residing on neighbouring molecules. To rationalize this phenomenon, a …

The idea that excitonic (electronic) coherences are of fundamental importance to natural
photosynthesis gained popularity when slowly dephasing quantum beats (QBs) were …

We report experimental 2D infrared (2D IR) spectra of coherent light–matter excitations––
molecular vibrational polaritons. The application of advanced 2D IR spectroscopy to …

The influence of exciton–vibrational coupling on the optical and transport properties of
molecular aggregates is an old problem that gained renewed interest in recent years. On the …

Multidimensional Coherent Optical Photocurrent Spectroscopy (MD-COPS) is implemented
using unstabilized interferometers. Photocurrent from a semiconductor sample is generated …

Femtosecond pulsed excitation of light-harvesting complexes creates oscillatory features in
their response. This phenomenon has inspired a large body of work aimed at uncovering the …

We report the first direct spectroscopic evidence for coherent electronic coupling between
excitons and trions in atomically thin transition metal dichalcogenides, specifically …

Tricomb spectroscopy unveils a new dimension to standard linear and nonlinear
spectroscopic analysis, offering the possibility to reveal the almost real-time evolution of …
