ABOUT THE COURSE:The 2023 Nobel prize in Physics recognized the pioneers of attosecond physics. In the first course of its kind in India, we will present a unified Iearning and training module on the fundamentals of attosecond science and technology, or ULTRAFAST. In this course we will learn Unprecedented Temporal Resolution, Real-time Observation of Electron Dynamics, Controlling Matter at the Atomic and Molecular Level and applications to science and technology. This course will be a perfect platform to blend the fundamentals with the state of the art in attosecond science and technology.INTENDEN AUIDENCE:Advanced undergraduate, Masters’ and PhD students in physics, electrical engineering, photonics, optoelectronics and other related areas.PRE-REQUISITES:Basic knowledge of optics and electromagnetism. A knowledge of quantum mechanics will be an advantage but is not essential. Requisites will be covered in the course.INDUSTRY SUPPORT:This is mostly for advanced further academic studies and research.
