Abstract

Femtosecond coherence spectroscopy is a family of ultrafast techniques that utilize ultrafast laser pulses to prepare and monitor coherent states in resonant or non-resonant samples. Among coherence spectroscopies, 2D electronic spectroscopy (2DES) techniques have recently gained particular interest given their capability of following ultrafast processes in real-time. Indeed, 2DES is widely exploited nowadays to unveil subtle details of ultrafast relaxation dynamics, including energy and charge transport, in complex media such as biological and artificial light-harvesting complexes and solid-state materials. Particularly meaningful is the possibility of assessing coherent mechanisms active in the transport of excitation energy in these materials. With the development of promising new applications and rapidly evolving technical capabilities, the enormous potential of 2DES techniques to impact the field of nanosystems, quantum technologies, and quantum devices is here delineated. Two examples illustrate this aim: semiconductor quantum dots solid-state materials and colloidal suspensions of plexciton nanohybrids.
