The 23rd International Conference on Ultrafast Phenomena
14–19 July 2024, World Trade Center, Barcelona, Spain
About Ultrafast Phenomena The Ultrafast Phenomena Conference series began in 1976 and is held every two years. It is widely recognized as the premier international forum for gathering the community of scientists and engineers working in research and technology related to ultrafast phenomena. It brings together atomic, molecular, and condensed matter physicists, physical chemists, biophysicists, and scientists developing new tools, methodologies and techniques, all working on the science of ultrafast phenomena. These phenomena cover the time scales ranging from picoseconds (1 ps = 10-12 s) to hundreds of attoseconds (1 as = 10-18 s).
In the recent past, the field of ultrafast phenomena has moved ahead in a breathtaking fashion, thanks in part, to the development of new laser-based as well as accelerator-based sources of ultrashort pulses of electrons and light, such as high-harmonic generation, few-cycle optical pulses, sources of short wavelength radiation such as x-ray free electron lasers. The spectral range of ultrashort pulses of radiation has been extended to the long wavelength range such as Terahertz radiation, and the short wavelength range such as vacuum-ultraviolet and the soft and hard X-ray domains. Together with the development of new methodologies, e.g., multidimensional spectroscopies, THz spectroscopy, electron-based (EELS, PINEM, UED, etc.) and X-ray-based techniques such as serial femtosecond coherent diffractive imaging, these great leaps forward are delivering an impressive degree of insight into phenomena both within atoms and between atoms and up in scale to macromolecular systems.
At the same time, the flexibility in methodologies opens perspectives for major applications in the fields of solar energy, molecular electronics, optoelectronic devices, biomimetic devices, etc. Finally, all this is accompanied by an improvement in theoretical models, strongly supported by the increase in computational power, which are indispensable for our understanding of phenomena on such ultrafast time scales.
